I'll try to repro mmc3 game but prg size 64k and chr size 8k. so it must use eprom No. 27c512 and 27c64 that have 28 pin . How can I rewire it to mmc3 board 32 pin? (TLROM)
You can just use the large EPROMs your board expects and replicate the contents until they fill the entire chip.

That was quite a long time ago! I don't even remember if I finished that cart or not. I don't think I did, since I can't find a TLROM board in my box of devcarts...

How can I do that, please explain?
To make a file twice as big, put this in a Windows command prompt:
copy /b somefile.bin+somefile.bin doubled.bin
For example, if you have 32KB of data to fill a 256KB EPROM you can just write the same data 8 times. You can generate the file with the repeated data like this in the command prompt or in a batch file: copy /b prg32.prg + prg32.prg + prg32.prg + prg32.prg + prg32.prg + prg32.prg + prg32.prg + prg32.prg prg256.prg
OK.
I can do it.
Windows command prompt: copy/b file64.prg+file64.prg 128.prg
I got file 128.prg but it's not work(dark screen)
