And for windows, you can just drag the ROM to the program, or you can run it in a batch file with:

Code: Select all

ReadNES3.exe ROMNAME.NES [Number of times to repeat program bank] [Number of times to repeat character bank]

If you're in linux, I think I added a linux file to that ZIP, but if not the source is there, just compile and do the same. Shell script would just be:

Code: Select all

./ReadNES3 ROMNAME.NES [Number of times to repeat program bank] [Number of times to repeat character bank]

That should be all ya need. Good luck.

Ok I will try tomororrow it's bit late thanks

i tried to split a nes file which was legend of zelda then looked for a Donor Cart and it is a snrom according to this link http://www.thenesdump.com/Mappers/SNROM.htm it has no CHR rom so i think i do not need to split zelda hope you understand first time playing a nes last week i was born in 1993 so this is very very new to me thanks

Even if a ROM has no CHR-ROM (meaning it uses CHR-RAM), you still have to "split" it in order to remove the iNES header (i.e. the first 16 bytes of the file).

so just split the Nes file and burn the prg file to an eprom and that's it ready for the donor cart and what eprom do i use thanks

[tokumaru]

Yeah, just burn the PRG-ROM. Most 8-bit EPROMs will work, just keep in mind that EPROM sizes are specified in Kilobits, not Kilobytes. Take a 27C256 for example: it holds 256 Kilobits, which is 32 Kilobytes. If the PRG-ROM is 128 Kilobytes, you need a 27c010 (the 010 stands for 1024).

Also, you can't just drop the EPROM where the original Mask ROM was, because the pinouts are not 100% compatible. You have to compare the pinouts of both chips rewire anything that doesn't match.

OK thanks for the help i know i have solder and wire the chip in i was wondering if you could use a zif socket and then just swap the chip to another snrom chip like Bard's Tale is that possible thanks

Yes, that would work fine.

Just google for the ROMS. You can't post any copyrighted ROMS here though!

Guessing you read it too fast For EPROMs, ebay is decent one of the sellers there also has their own site but they ship from china 'buyicnow' I think I've got good stuff from them in the past. Someone else might have a better supplier stateside if you don't want to wait as long.

[3gengames]

Haha, I read it thinking he really meant ROMS, heh. My bad. But Futurlec has some ROMS, Ebay, Digikey maybe.

does anybody here use the GQ-4X PROGRAMMER is it worth £80 is there other ones that does the job for less then £80

[proveaux]

Yeah. It works well. I haven't any problems with.
