Hello everyone, this time I have a Konami Asterix board that I got from the Arcade Museum forums.
I bought it as non-working "error with 2 chips" at an affordable price.
This is the board:

I immediately attached it to my JAMMA Test Rig and powered it up.

Indeed, we see 2 defective chips on the board's ROM Check screen – 2F and 5F.
When examining the board, we see that 2F is a RAM chip while 5F is a ROM chip.

The 5F EPROM (TMS27C512) is already socketed, so let's dump it and compare it with MAME via the ROMIdent site.


The ROM looks fine and matches what it should be. For good measure though, I'll rewrite the dump back to the EPROM.



Then, while I'm at it, I'll write the MAME equivalent dump file 068_a05.5f to another EPROM (W27C512) that I'm sure is good, so that we can try both.
