SMB For Sega Genesis - Eeprom question..

Post by TheDeath »

Hello!
Please can you help me figure out how can i double up the size of this game in order to burn in on a 27C160?
The game size's about 64Kb (it's the Super Mario Bros Maitrus 2010 version) but i only have 1MB 27C160 eproms..

I usually do that with snes carts among with Lunar Expand.
I have tryed the same with this genesis game but it wont work..

Weird thing is that i have tryed first on mine emulator, correct the checksum, and the game was working fine..

Bad thing is that i have 40-42 pin eeprom with that size (64Kb, 128Kb,512Kb) but the pinout of these are totally messed up compared to the mask roms, they also miss pins like A18/A19 wich i think they are necessary.

How can i fill up this rom?
I got a willem programmer

Thank you for your help!

Is it linear and headerless (.bin or .gen) or interleaved and with a copier header (.smd)? If headerless, you can just go to Command Prompt and

Code: Select all

copy /b file.gen+file.gen bigger.gen

No MD game relies on mirroring, you can only program the first bit of the chip with the ROM and it will work. There's no need to double+ the image size (unless your burning tool is kinda limited)
