Hi, I'm planning to make a smb2j on a cart. I'm using 2 x 49f040 plcc32. I know that this chips are not the best choice, but they are the only one i have. i hope they will work. As donor cart i used Super Mario Bros 3. I'm using loopy's mm3 hack. the file's size 81,936. I've used ucon64 to obtain the chr and prg files with this command: ucon64 -s smb2j.nes I don't have a programmer, but i have this: http://www.ziegler.desaign.de/readplus.htm#GB_Flasher and i made an adapter like this: http://www.ziegler.desaign.de/c3cart.gif So now the chips are programmed. For the PRG rom, all the connections are pin per pin, except this: 49F040 ..........PRG pin 1 (A18)--- hole 2 pin 2 (A16)--- hole 24 pin30 (A17)--- hole 1 pin24 (OE)--- GND The BIG question: will this thing work? and where do i connect the WE pin for 49F040? Next will be the CHR rom.
