Making Super Nintendo Burn In Test Cart Repro

Post by paxtammy »

Hi, I am doing SNES console repairs and I thought having this cart would be helpful. I am familair with making SNES reproductions, on custom PCB boards, not donors- I have the REV D rom, but its only 512kb and I am unable to pad the rom so i can fill it and fit unto a 1MB 27C801 eprom, when i open the file in wasabi, it gives an error - also using ucon64, it shows the checksum is bad, so when i try to repair with IpsAndSum, it is all zeros and cannot repair the checksum.

Anyone have experience making a repro of this cart that can chime in with some advice please?
Am I ok to skip the rom padding and skip the checksum fix? Will cart work?

I looked up wasabi, and this review sounds like the same thing. It needs to be a size divisible by 1MB. They recommend using Lunar Expand on it first.

I wouldn't worry about the checksum. One would think a test cart might actually care about it, but if it passes on the emulator it should be the same on the SNES.

So i did use Lunar Expand on it and now its 1024kb (8Mb)
However Wasabi tool will not load it, same error as before. I think it should be ok, I will test it. Since its going unto a 27c801, it shouldnt need padding anyways! Thanks for your comment and direction!!!!
