So, I got EPROMs in the mail today and plan on reburning all the roms since I can't find out which are bad, but the MAME set doesn't have a file extension and the burn process insta-fails at 1%. I imagine I need to convert the files to .bin... What do I need to do to get this working?

Thank you again for being willing to endure my stupid questions.. :S

Just change the file extension form .[whatever] to .bin.

Ex: gl-c1.rom becomes gl-c1.bin.

When you get more advanced, you can even try changing the file name. :D

but they don't have any existing extension..

I went ahead and changed it to .bin and this is what I get:

For Kicks I decided to re-burn ROMs 1 and 2 and they completed without issue.

Make sure you have the right jumper setting too on the adapter board. You can also remove the 10uf cap on the adapter if nothing else works, see if that changes anything.

Yeah, saw the silk screen next to the jumper. It looks like the burn speed was the trick, its progressing nicely.

That's one thing I really hated when I had one of those, can be so picky at times.

I usually don't touch speed when burning. The slower the more burns you get without errors. Just like burning CDs.

ok, in total out of 12 EPROMs:

7 Failed
5 completed without errors.

Of those 7 failures:

2 were burned too fast
5 failed the blank check.

Gotta find myself a UV eraser.

In the meantime just use the sun, maybe 45 minutes.

Free UV baby.

Are you using one of the Willem burners? Sounds like a right pain in the ass.

You can use a UVC germicidal lamp and a box if you don't want to wait on shipping. A UVB reptile lamp will probably work also....just might take a bit longer.

How do these boards use 32Mb chips? Can you set the jumpers and use a regular CPS2 PAL-G to address them?

You can't use the standard B-board Pals. You use the one that is on the black pcb just change the jumpers. If you look at my video you will see that I used a pcb converted to SFA3 with 32mb roms.

The pal can handle most games on the CPS2 system but there are some that it simply cannot like DD. In these cases I think there are two options:

1: Someone write a custom PAL to play these games
2: rearrange data on the eproms to accommodate the current pal.

Not sure if either will actually work.

Please tell me you went with one that actually uses a bulb and not an LED.

Also, on the Auto Run side, check Blank Check. When you burn an eprom it will perform a blank check first to make sure the chip is blank before it tries to program it.

I have one of those. It works great. And Iirc, it has a bulb.

Only problem is that it only holds like 5~6 roms at a time. And the roms in the middle of the tray get the best light and erase the fastest.

Was thinking about getting a second.

Only down side is that it took "forever" for mine to arrive from "China." :lolz:
