7800 Emucoder

WANT!!!!

More awesome every time I open the thread

I'm mostly referring to Choplifter, actually. It's playable, but compared to the wonderful SMS version which came out before it, it is terrible. Big, dumb looking ugly sprites. very little detail. One level. Boooo!

So they made 3 awful ports. What I normally do is play Karateka on the PSP version of Prosystem, turn the FPS limit off, and it runs at around 72FPS, which is actually perfect, and the lag is non-existent.

Fine. But Apple started before the VCS was released, and in 2013 they are still one of the biggest players in the home computing market, whereas Atari hasn't even been a bit player for close to 30 years. Atari's glory years lasted from 1977-1983. Apple's lasted from 1984-2013+. They aren't even remotely comparable.

Apple started before Atari.

What would be really cool would be to hack the 7800 NTSC bios so that it has a built-in game like the PAL one, and so it was something other than boring Asteroids. Maybe Xevious, or Joust. or Donkey Kong. or Ninja Golf. or Pole Position II. Or put a socketed slot for that EPROM so people could change it to whatever they want.

Gorf posted the demo ROM shortly before his flare up and eventual exit.

I don't know that it was just a Canada problem. I live in Boston, MA and I was around 15 when the 7800 came out so I used to scour all the local games and toy stores for new releases and many of the later games like you mentioned never made it to store shelves here. Besides the Evil Eleven launch games, I think the only ones I ever saw make it to store shelves were One on One, Summer Games, Winter Games, Hat Trick, Jinks, Choplifter, The Absolute Entertainment games, and Froggo games. Most of these latter releases I never actually saw until I found this website in the early 2000's.

the one I explained is even simpler than that. Instead of soldering two new resistors at 6.8k and 18k to those points, just clip the already existing 6.8k and 18k resistors right there on the motherboard at their top posts (towards the back of the console) and solder them together three. You don't even really need the 1uf cap. the resistors are already there on the board. just use those.

That's basically the same exact mod as the "Easier 7800 composite Mod" thread one.

Use a different mod.

In my composite mod, I clipped the top connections(towards the back of the console) of both R5 and R6 from the board, leaving the bottom posts still attached to the board (the ends facing the joystick ports), and soldered the clipped ends of the resistors together, and this constitutes my audio signal. This gives perfectly mixed audio between TIA and POKEY.

How about "Oh Noes!!!"

I know there are a few homebrew cart makers on here, so I'm looking for recommendations on EPROM burners for 7800 games for those who've used them. There are so many great hacks and unreleased or out of print homebrew 7800 and 2600 games out there, and I'd really like to learn how to make my own. Thankz.

That pot doesn't actually adjust proper Tint/Hue values in the conventional Green ~ Red tint adjustment manner. It adjusts Color BIas, so even very slight adjustments alter the color bias tremendously. It turns Brown to Blue and Green to orange. it's not really a good way to adjust tint. The problem with the green push on the newer revision 7800s is the values of the resistors in the Luma ladder. Too strong Luma in the signal skews the overall color balance toward green. Too much chroma skews a bit red, but mostly it just over saturates the picture with color, and colors tend to bleed and smear. What I typicially do in video modded 2600's and 7800's is replace the Lum0 Lum1 and Lum2 resistors in the Luma ladder with 10k or 5k potentiometers and tweak them until it looks better.

I would be very interested in the Kung Fu Master if it had the jump kick...

You baked potato, bra?

it's essentially the same as the "easier 7800 Composite mod", but in the 2600 you need to change the values on the Luma resisitors to compensate for lack of brightness. I will do a picture blog of it in this thread later, and then show comparison photos of the 7800 vs. 2600.

So has anyone ever investigated if it's possible to re-configure or replace certain resistors or otehr components in the 7800 to make the colors in 2600 games appear correctly? I just recently finished up a composite video mode in my recently acquired 2600 jr, and man - I forgot how much different and washed out the color was in 2600 games on the 7800. I mean, really really bad. Anyone?

I never did, and never will. I have no interest in hording overpriced "collectables" to sit on a shelf in some protective casing. I like playing video games, particularly retro games. If I can acquire the original system and carts/discs to play them in their original format for little to no money, great. If not, there is always emulation. I've gotten a lot of my stuff from the swap area at the town dump in my town for free. For the games that I do acquire, I do so for the sole purpose of hooking them up and playing them. If I'm not going to actually play it, I'm not buying it. So I have no need for the ultra rare games like Video Life or Chase the Chuckwagon, which absolutely suck to play. That's one of the beauties of emulation - you get to find out if games suck without having to buy them. I have no need for boxes, and care not about the condition. Typically I will tear apart classic consoles to video-mod them for use on newer TVs.

I used this circuit in my new 2600. It's the same as the "easier 7800 Composite mod" from the thread in the 7800 forum. Unfortuantely as-is it produces less than stellar results in the 2600. I needed to adjust the Luma Resistor values to get the overall brightness levels anywhere near passable.

AWESOME.

Also: NTSC only, thanks.

So I'm now the proud owner of a functioning 2600 jr "small rainbow" console. I really do like the slick styling if the Junior, especially the small rainbow version. Never really liked the old 70's porno font/wood paneling/radiator grille models. Anyway, I'm wondering which DIY composite mods folks would recommend here. I've searched a bit, but most threads on this subject are inconclusive or have links to no longer existing external web links. I'm not interested in S-Video mods of any kind, because none if my 3 televisions support s-video. And I'm not planning on getting one that does. Also, I prefer the true DIY projects where I build it myself, as opposed to the $30 eBay boards pre-populated with >$5 worth of parts. Thanks
