Help with TSOP programming.

So, I have some M29F032's mounted on TSOP boards, as well as a willem adapter made up.

My GQ-3X calls out the chip correctly, it programs and verifies without an issue, but I cant get my SNES to actually boot anything from these.

I am trying to write an English translation of Seiken Densetsu 3. I take the rom, which has a good checksum according to SNES9x, strip off the header and burn.

I guess the SNES hardware may have some other issue with the translation I am using, perhaps I should back up and try another rom image to see if that works..

I am using the type 2 adapters from buyicnow.com: http://www.buyicnow.com/vp.php?pd=1986

I do know that the A20 and A21 lines are reversed, but I am programming them via the willem dip adapter, so that should be programmed reversed as well.

Perhaps I should just look for a confirmed working on actual hardware 32mbit ROM image and work from there? For those of you who actually have done this, what images have you used, and if I could get some checksums to verify my images that would be most helpful.

Nevermind! I figured out my issue.. I was deleting the headers, which I was not supposed to be doing.

I figured this out by reading back an original SD3 maskrom on this willem adapter and checksuming it to my rom files. I now have a working TSOP cart.. now if only I can steady my hands to make another.....
