Here's the end result of discussion threads like this: People are selling fake Earthbound carts with boards like this now, claiming they are authentic. Anyone here want to take credit for this one? I beg to differ...the end result of threads like this is that people are able to run whatever code th...

Simple question that could be included in the doc
Max current draw of a cart in the cartridge slot?
Some quick thoughts: One ROM uses 40mA while operating (checked the datasheet for the ROM) and some carts have 2 ROMs so thats at least 80mA.

I couldn't even assemble the code if I added those 4 lines. The assembler chokes at an LDX instruction in SetCursorPos that is trying to load an immediate larger than 8 bits after you've set all the registers to 8-bit with SEP #$30. Yeah not sure how i was getting the code to assemble...i restarted...

I don't know why Snes9x crashes. What I can say is that you should ditch Snes9x right away and use BSNES instead, as it's a lot more accurate and also has a debugger. What were the register size bits set to before the instructions you inserted? You should make sure they're set to the same as they w...

just of interesting note, i obtained an older revision of the cart PCB and it, in fact, has 1 mask ROM. (+ MAD-1 and SRAM) so it does look like at some point down the road it was cheaper to do the 8/16mbit combo and just decode it differently. now i have another board to hit up with the multimeter :P

LoROM means A15 is ignored, and now you're down to 32 Mbit of address space (without doing a Lo-Hi combo like Tales of Phantasia). Perhaps during the Super NES's commercial era, a 16 Mbit mask ROM and a 4 Mbit or 8 Mbit mask ROM combined were cheaper than a 32 Mbit mask ROM. Banks 00-3F give you 64...

snes cart hacking: replacing mask ROMs
hello all, I need some help/explanation of how the NBA JAM TE cart is designed. It's a 24 Mbit LoROM cart with 2 ROMs, SaveRAM and MAD-1 decoder. http://www.snescentral.com/pcb.php?id=0111&num=0&side=front Here's where I'm getting confused: 36-pin ROM has 23 Address lines...(A0-A22) which gi...
