OH! ok... I'm trying to think of how to check for this. If I *do* change the RAM we use to stick to the $1800-$1FFF area, there shouldn't be any contention on either the cart or system ends, do I have that right?

Thank you I was letting it sit as well, but I have an actual cartridge. I guess I should let it sit in the dragonfly to be absolutely sure. Thanks, guys

Hi guys! Thank you! I don't believe it is that, only because the PAL BIOS uses $23XX and $27XX without issue... We're (RevEng and I) are using $18XX and $27XX. I've actually left the cart in the slot from the beginning (cold unit giving corrupt menus) to completely warmed up (no corrupt menus at all). Ok, I'm going to have to BIOS mod my other unit to see if it happens on that one. That may lean toward the RAM issue being the culprit.

So *nobody* else has had this happen...?

I haven't had an issue with any normal / retail games so far, haven't found any with the homebrews that I've tried (Ive even tried 'Tainted Love' - the 512K cart!), nor with the Dragonfly. Now granted, I don't have that many stand alone games, so I can't test with everything, but I've tried some of the ones I thought might give it a hard time (like Bentley Bear). It's just this CCII thing is bugging me. The original NTSC BIOS works no matter what the temperature of the machine, as does the original PAL BIOS, so what gives? *EDIT* - I'm just afraid that if this is happening with the CCII, it could happen with something else.

Ok, being that we cannot get past this last issue, this custom BIOS is put on hold indefinitely until a resolution is found.

Thank you. Ok, so I have to ask: anyone else experience this?

Good Morning: Thank you so much for the compliments! (Although it isn't a hack, it's a homebrew ) Can you tell me at what point the crash happened? Was it during normal gameplay, or after clearing a board, or after dying, or ? Thank you, Bob

Two different screen modes. Now, if Galaga was turned into 320 mode...

Here's a weird issue I wanted to throw out there... if anyone has any ideas... The BIOS works great - except for the CCII. It seems that if the console has been off for a bit, the CCII menu mostly comes up corrupted. Powering off/on the unit can make the menu come up normal about once every 15 boots. If I leave the unit on for a while, the longer it is on, the more often the menu comes up normal. Up to the point (I would say after leaving the unit on for about 20 to 30 minutes), then the menu comes up correct - every time. I've *never* seen this before, and I'm curious to know why the cart doesn't react that way with the standard NTSC bios or even the standard PAL one. Does anyone have any ideas? Thanks!

I also used Bruce's method. That was the easiest, but it only allows up to a 16K EPROM @CPUWIZ - You are a madman! Love how clean that board looks

I just watched the developer spotlight, for the sole reason of seeing what people wrote in the chat (I couldn't see that or even the game screens during the show). A couple of people ( @-^CrossBow^-, @sramirez2008 ) picked up on what was going on in the background. So for those of you who watched it now know what @RevEng, @Trebor, and I are working on - the Non-Interactive Title Screen as a BIOS with a small non-cart game. A couple of things: - It hasn't been released yet: although we have figured out why the ARM 2600 games wouldn't originally play, we are still working through issues with the CCII showing up with a corrupt menu about 1/2 the time. - I will be making a small (8K), exclusive game to this BIOS for when there is no cart inserted. - I had a third point, but I can't remember what it was.... BTW, Yes, that was a 3-D printed case that you saw, I am still working on the top of it (which is why it wasn't there). I plan on calling it the '7800 Jr.' case, as it will be smaller than the original. It will also be flat, with the front ports and switches easier to access, which should make the Atarivox fit nicer in the 2nd player port. There will have to be a small modification to the RF shielding bottom (for people who still have theirs on) in order to make room for the screw posts.

Ok... I think I need one of these...

Thank you guys - yesterday was a lot of fun. I really appreciate the kindness you guys show me. It makes me want to do more here. I say it all the time: you guys are AWESOME!

he he...

You are absolutely right. (and thank you for the compliments). I moved the Namco copyright to the bottom. OK - THIS is the final one. Galaxian.A78 Galaxian.BIN

Thank you so much! Being that I already messed up by posting the RC before next week (it was supposed to be during the developer spotlight), I did another update (I added the 'Game Over' text to the attract mode demo) If nobody finds any bugs, this will be the final one. Thanks again! Galaxian.A78 Galaxian.BIN

Ok, so we are in agreement. Good...

Just a curiosity thing here: I enabled Kangaroo mode this morning before work, as it would be great to be able to use that third color. However I wanted to get an opinion on this as doing so has the following effects: - You don't see the stars during the attract mode (except at the VERY bottom of the screen) - You don't see the stars behind the swarm when playing - You see the 'black boxes' behind the diving enemies when they are on top of the rest of the swarm - anything else I may have forgotten. Doing this will allow me to fully use the 'blue' for the flagship and the player, and possibly a third color for the other aliens, if I can re-work it. I forgot to post it this morning, so I'm doing it quickly now while I'm waiting for something to run here at work... What do you think? (Personally, the black boxes bother me too much). Galaxian.A78 Galaxian.BIN

Hey guys... RC1 attached. - Changed the display of the reserved lives to when the player appears on the screen, as mentioned above. - fixed Rapid Fire - Changed the Shot sound slightly - Slightly adjusted the difficulty (made 'normal' a tad easier). - Changed the alien diving sound to continue after the alien wraps the screen. Enjoy! Galaxian.A78 Galaxian.BIN

Yep, I already fixed that I'll be working on the last few items after work today. Should have an RC1 by tonight.

Next WIP... Updated: Added 'demo game' to attract mode Added 'rapid fire' option Things left: Work on two sounds: Player Shot (the sound itself), and Enemy Dive (the 'lowest' part where it just loops) Possible Flagship + 1 enemy left issue. Haven't been able to recreate it as of yet. Maybe tweak 'Normal' difficulty a little more? Still seems too hard to me. Galaxian.A78 Galaxian.BIN

@sramirez2008 - What was their status? Both in the swarm, both in the air, or which one was in the air and the other in the swarm? Also, do you remember if the flagship originally had escorts and you shot them, or attacked without escorts? Thanks!
