Question about ROM programming

[wilianpc]

Hi! Congratulations for this beautiful project. Sorry if these are noob questions, but there they go:
When writing in the EPROM, should i byte-swap the ROM?
If i use a regular SRAM (ex. CY62256) with battery, should i keep the pin order (A0...A14)?

Hey man, thanks!!! Don't worry, every question is welcome

Yes, you should, most common Genesis ROMs formats are byteswapped for some reason.

About the SRAM, I supose that it should work, but I never tried, I also supose that you will implement the battery circuit yourself right?

Thanks for your kindness! Yeah, It's a popular common-emitter transistor circuit, with two face-to-face diodes as the "VCC" for the SRAM.
