Can someone run checksums on these roms for me? I need 4 character checksums, not CRC. Troubleshooting one of these boards and from its behavior it looks like its running out of code and resetting in the attract screen. My USB floppy is loaned out right now, so I can't get files to my ancient dos box programmer without huge hassle. Rom type is 2332 prom (not eproms).

Zipped romset is attached. TIA.

<in best Butters voice> Awwww dangit! Forgot about that page.

Just for reference, the best way I have found to read these 2332 proms is to use an additional socket and bend pin 21 out of the programmers ZIF socket. Hold pin 21 low and read as a 2532.

Hamster's online romident tool will calculate and report the "plain ole" checksum of ROMs:

Ignore all but the last 4 hex digits to get what's usually printed as a checksum.

AHH! so i just need to report the last 4 then, someone else mentioned it was wrong, i have modified it, and it should be good to go now :) , thank darren.
