PGM single game PCB assembly and troubleshooting

[dexa]

I just looked through my inbox, I don't seem to have it any more. I'll have to go through my stash of 27c322 if I can find it, though that may take quite some time.

Two things you can try:
- I just had a problem with crashes in another project, turns out the flux in the solder I used is not the "no clean" type. Make sure if you have flux residue on your PCB that you clean it off.
- Is the program ROM for KOV 2 a 27c322 or 27c160? If it is a 27c160 it may work if you close JP2. See if it boots into the game.

Good idea, I will check the KOV ROM again with JP2 closed.

It would be great if you can take a look at your 27c322 stash as it seems like @iq_132 is MIA and I dont think anyone else has the source code to the ROM generator tool

Success! Puzzli2 and Puzzli2 Super work now with the fixed ROM. Switching versions with JP2 works too.

Huge thanks @iq_132
Small addition for your tutorial pdf: you have to close JP1. Else the game will boot into an error.

iq_132 did a lot more work than I did...

Finished building my last cart tonight (ESPGaluda) and noticed that I have an off graphic glitch.

It only appears on the Ageha Sprite on character select, and EVERY boss sprite.

Did I burn a chip incorrectly or is maybe one of my EPRoms bad? Everything else plays and sounds perfectly, it just seems like a corrupt sprite layer or something.

Anyone ever see this before?

my esp also has faint graphics glitches. the clouds on character select is noticeably flickering and during gameplay sometimes the bombs glitch. I think fluffy at some point directed me to a chip to look at but I never got around to it.

I figured it out. When inserting my EPRoms, one leg on A2 had curled under and wasn't in it's actual socket. Sorted that out and reseated it, and now everything is 100%!

You would be surprised how often that happens....
