SNES SA1 cartridge adapter being made with level shifter
by on (#150302)
Hey group,
I've been working on an adapter for the SA1 cartridges. I cringe every time I see someone making a Mario RPG hack using the 3volt roms in a 5 volt system. Yes, yes... they use a voltage regulator for power and the byte pin, and WE pin....but still the address lines are getting hammered with 5 volt signals. Anyways, my adapter is using a voltage translator and has a few other features that some might find interesting. This is just my prototype so the actual production version may be a little different. Of course, all parts will be pre-mounted except for the rom. I'm not sure of pricing yet as I don't have production pricing yet. They should be less than $20
Just wanted you guys to be aware that such an adapter will soon exist. PM me if anyone is interested in these. Thanks!

Cool idea! Would it be feasible to make a similar adapter for regular SNES mask ROMs? If so, would it be cheaper than a 29F032/29F033 flash chip plus the TSOP->DIP36 adapter used in most SNES repros out there?

Feasible, absolutely. Cheaper, doubtful.
