Homage to the arcade version.And only for those who worked at arcades and actually saw that stuff.
Lots of arcade games would give you 1 credit when you un/replugged it into the wall. We used to do this at one of my local arcades.

Turning the brightness down does help, but on my TV, what happens is that other games are then negatively impacted. Particularly ones with colored/green backgrounds - specifically Commando. It doesn't make it terrible, but it's noticeably darker than it should be.I'm really nitpicking here though. This mod is just plain awesome. It's cheap, and it takes all of 15 minutes to put together, even if you're a complete hack with a soldering iron.
No worries, any information is good. If we can change a couple of resistors or so to squeeze out an even better picture then I think that is worth trying. I always like simple solutions to seemingly complex problems and I am glad I can help provide one. I don't have a Commando cart but perhaps a 2600 pitfall cart shows the same symptom. If you have a pitfall cart, I would love to know that. Otherwise, I guess I will just have to buy a Commando Cart (like that is a bad thing!)
Actually, I just redid the mod. My first go-round was sloppy, I didn't cut the tails on the resistors, so there was a lot of bending and folding going on. I just wanted to see if I could get it to work.
Also - Like I said, I couldn't find a 75 ohm resistor, so I made a 77ohm circuit putting a 47-10-10-10omh series connection. That was a pain in the ass, so I dropped one of the 10's to make it 67ohm.
Doing that, plus using a NEW solder roll as opposed to an old crappy one that was probably cold - the ghosting isn't really an issue now.
Pitfall looks fantastic.
I have a Cuttle Cart 2, so I can pretty much test anything.

It's not 7800 sound that's the problem. It's POKEY sound. The 7800 sound effects are fine. But the few games that use the pokey for music - Commando, Ballblazer, Froggie, Beef Drop, have no music with yours.Also - there's a bit of ghosting when the brightness is turned up enough. Think that 91k replacing R15 will fix that?
Oops! Now I understand. I don't have any of those carts to test. Where did you pick up the POKEY sound?
replacing R15 with a 91K will actually bring the brightness down a notch. I don't think it will help with ghosting. Many Atari systems have a slight ghosting problem due to the way the color signal is joined with the luminance signal. I guess Atari figured since the systems will work through RF anyway, the ghosting won't be noticed as the RF degrades the picture anyway.
When I hooked my 7800 up to a composite monitor and my TV and I don't think I noticed any ghosting but I will look again and see. I wasn't looking for any either, I was just amazed at how much better it looked. BTW, nice work on your 7800. Its good to have multiple people try something like this. Maybe we should call it the 7800 $10.00 super video Mod?
The ghosting is more like an bright aura around images. If you play any game where you have a black background and lots of bright characters, you will see it. Robotron is one I see the ghosting(bright aura around the each image). Turning down the brightness on the monitor is what I do, but an internal solution would be best.
The sound was important to me because Needing to play Beef Drop, I had to join R5 and R6 puts all the signals together if I remember the reading the schematic correctly.

2. - the audio portion is a problem in puppet mark's version. there's no pokey sound coming through.So I did a combination of Puppetmark's video circuit and Almost Rice's audio circuit.
Interesting. I checked again and I am getting 2600 and 7800 sound. I wonder what I am missing here. How did you hook up the audio?

While I had her open, I changed the LED to Yellow.

Just did this mod.
AWESOME!!!!
Two things:
1. - I couldn't find a 75ohm 1.4 watt resistor at radio shack, so I used a a 47ohm + 3 10ohms in series. 1000x better than RF though.
2. - the audio portion is a problem in puppet mark's version. there's no pokey sound coming through.
So I did a combination of Puppetmark's video circuit and Almost Rice's audio circuit.
Perfect. And I think it cost a total of like $10 at radio shack.

Make sure Jstella is working on your computer.This doesn't work in Firefox, though it works in IE.

I never really hated Karateka on the 7800, but then I never played the other versions.
however - 7800 Karateka is completely playable and actually FUN on PSP7800, when you run it at 333Mhz processor and no frame limiting, no v-sync. It speeds it up just enough to make the controls feel right, around 72fps, or a 18% increase in speed.

The signal was barely enough to get a signal on my TV and the image rolled. The amplified signal is a bit too bright, but I can adjust the monitor.I had the same experience. Without the Amp, it was unusable. If you change out R15 with a larger value, perhaps a 91K, it should decrease the brightness. This is purely speculation. I am fine with turning down the brighness a bit.
This is fantastic guys! thanks for all the pics.
I'm going to do this next week. I might even try the 91k r15 replacement just to see what I get.

I don't care about "pretty" at all, especially if it's all concealed under the case. I just want to be sure I have the right solder points and components to put this together. I'm off work next week and the wife is out of town, So I have liberty to mess up the house with electronics work & tuning my HDTV, and have plenty of time to clean up.
-
Can you guys post some pics of this, especially the soldering points - and components used.
I've wanted to video mod my 7800 for a couple of years now, but the 8-Bit domain one is way overpriced and the horror stories of ordering from him didn't encourage me.
-
WAY overpriced.
The console with these two terrible games alone can be had for $20 easily on Ebay, and the 8-bit mod is only $39 - new, this one's mod is used and has been owned by at least 2 other people at this point.
-
Sealed, I'd say between $50 and $100.Hah, damn... I'll probably just keep it then.
Don't listen to Shadow, he's a true noob that continuously pretends to have a clue.
I've been into Atari since 1981.That doesn't mean a thing. Your still a huge noob who doesn't have the slightest clue about rarity or value of atari stuff but you still flap your gums like you do on a constant basis. I find your creepy wacko self pity threads in the gerneral chat amussing though, why don't you go do some more of those? You know alot about self pity and being a creep and no one can question your authority on that.
*CLICK*
YOUR A CREEPY NOOB!
PROMISE!
and from what I've read around here Shawn, you're kind of a loudmouth like Zylonbane, and also something of a price gouger in the marketplace forum section, who tries to drive up the price of stuff to milk a few extra bucks from the uninitiated.
we all have our faults, shawn.

That's why I use USB connect and not other software apps for dumping my UMDs on the slim. One stop shop.
As long as you have some way of making an ISO out of the dump. I thought that just let you see the disc at the file level. (But then that would mean that the USB mode would be faking a FAT filesystem, so maybe it really gives you access to the raw .ISO and a simple dd copy would do the job?)
When you enable the USB connection in the recovery menu, or using the XMB VSH menu to connect to the UMD drive, it shows up in windows as an ISO image, and you can simply copy the entire image to your PC.

no point in 3.52 anything for me. I am interested in running games like wipEout pulsE, Crisis Core, and some other very new titles that require 3.71 and up.My compatibility issue isn't with the firmware--it's with the Slim PSP.
One thing I've toyed with is loading time Machine on at least a couple of large memsticks, and maybe adding a physical switch into the batteries to switch them to and from service mode at will. I don't feel like lugging a JigKick battery around just for the occasional UMD dump. On that note, I might go ahead and set my chosen battery pack to JigKick anyway and load up Time Machine on Slim's memory cards just for UMD dumping. At least I could dump my UMDs when I get them home.
Hmmm, the wife's asleep right now, that mean's the phat PSP is not in use. Maybe I should go ahead and make some dumps to my computer, then I won't have to worry about Time Machine at all.
I have a fat psp running 3.52-4.
I have Wipeout Pulse, Crisis core, etc.
They all run fine. There isn't a single PSP game out that doesn't work with 3.52-4. Not one.
The idea that certain games require the newer firmware to run is a myth, Sony gave up on enforcing that practice a long time ago.
-
Now I just use the best UMD Dumper.bittorrent.
The difference being that Shadow wants to run the games he owns from a memory stick, not "liberate" games he doesn't own from the internet. Of course even ripping games you own is legally questionable at best. I'm not judging or objecting....just sayin'.
-Tim
I realize that.
Also - this thread, for a lot of reasons, makes a great case for the fact that DAX's custom firmware was at it's perfect state at 3.52-4OE, and should have stopped there. Every release since has been downhill on the compatibility scale.

That price is ridiculous. Anybody who would pay that is retarded! You could buy all the 2600 cartridges and 7800 ones you could ever want for that price.No, you can't. there are 10 or more 2600/7800 games taht go for more than that all by themselves. that price is high for a CC2, but considering they were $200 originally, and Chad sold them pretty much at cost, and they are now out of stock and not making any more, that price is not so ridiculous.
As I said before it is a pirating device. You are quoting that you cant buy certain games for the 2600/7800 because there too expensive. So you get this and play a game you dont own. Am I saying something wrong? You are basically quoting that you can pirate games you dont own with this. I have nothing against it, I do the same. But 500 dollars is stupid. 200 dollars ok. I bought a megacart from Tototek.com that allows me to load genesis cartridges that are less then 24 megabit from my sega cd and it is less than 100 dollars. Better deal! You can buy every 7800 game out there for alot less. Plus get some of the good 2600 games. Most of the 2600 games are terrible so who cares if you have them all. Its just not worth 500 dollars!
You really don't have the slightest clue what any of this stuff is worth.
-
There are alot more funner games on the genesis IMO and it is far cheaper. As far as the Atari 7800, I dont think I would need to buy every 7800 game if most of them are not that great. I would just buy the good ones. So I am sure I would stay well under 500 dollars. I already have, I have all the 7800 and 2600 games I could ever want and I may have spent 130 dollars in a period of 6 months.This is an Atari site.
If you don't like the games so much, and prefer Sega games, why are you here?
To troll?
-
Its not like its a collectors item, its more more like a pirating device. OOOOOOOhhhhhh did I say that? hehehehe!You're a dildo. and your avatar is gay. oooooo did I say that???I!!!!1LLLO110LOLOl .

Anyone know of a UMD dumper that can run on a Slip PSP? I want one that can dump the disc directly to /ISO similar to how the UMDDax dumper works on the phat. Dax's dumper only seems to work on the 1.50 kernel, and if I'm not mistaken, you have to install Time Machine to whichever memstick you're going to be using in the PSP (meaning all of them), AND carry a JigKick battery to run it.fastloader worked great when I used it. But that's fat PSP. It should work if you have the 1.50 kernel installed.
Now I just use the best UMD Dumper.
bittorrent.

When was the last time you saw an action movie about gang members and drug dealers where when a deal goes bad, or the Cops infiltrate the gang, the action gets going with some child rape?
This is the dumbest question on the internet.

I pray nightly that Blue Ray falls flat on its face.....Sony owns enough mainstreamstandards....I think the future is online movies..to hell with all these room stealing
hard copies...click and watch baby...it is the wave of the future.
Online point and click will eventually destroy both HD-DVD and Blue Ray, and
rightfully so.
Are you stuck in a time warp to 4 months ago?
HD DVD is dead. Toshiba officially dumped it in February. All consumer electronics stores have pulled players and discs from their shelves.
And by all accounts, Blu-Ray isn't going away any time soon.

Works just fine on my CC2. What a great job, PMP!
MESS is just that, as far as 7800 emulation goes. Stick with Prosystem.
