I've been doing research on reproduction games lately, no hardware to do it but have been contemplating getting an EPROM flasher. After finding infidelity's Super Mario All-Stars NES and not being able to play it with my N8 I got curious and dug around to see if it was possible to even make this repro.
famiROM and nestopia say it uses 64K of SRAM, 32 for saving and 32 for WRAM but no games in existence use this setup. However, the NESDev wiki says that NES-ETROMs can be modified to support that amount of SRAM with the SL/CL15 solder pads. Of course ETROM games are absurdly expensive, but their FC counterparts are much cheaper. I don't plan on destroying any games anytime soon but I can't find any info on if the HVC-ETROM boards can be modified in the same way.
So is it possible to modify an HVC-ETROM board to support 2 x 32KB SRAM chips? Unless I'm completely blind I can't find SL15 or CL15 on the FC game boards.
