w1k Posted May 4, 2009 Share Posted May 4, 2009 Hello atarians.. Can i save my eprom to binary file? i have three other cartridges in my atari (3x eprom).. switching buttons i can load one of that three carts.. Is it possible? Quote Link to comment Share on other sites More sharing options...
Rybags Posted May 4, 2009 Share Posted May 4, 2009 (edited) So, the EPROM is inside a cart? You can copy them but it usually involves hot-swapping the carts. filecopy.zip That's my old BASIC Filecopy utility from years ago... it has a simple cart copier built in. Does standard carts, but not bank-select ones. Edited May 4, 2009 by Rybags Quote Link to comment Share on other sites More sharing options...
w1k Posted May 4, 2009 Author Share Posted May 4, 2009 yes, i mean dump content of cartridge to file.. but that is internal 8kb cartridges flashed in eprom in atari.. no external cartridges. here you can see: 3x eproms http://podstromami.com/galleries/atari800x...kb/PIC_0062.jpg http://podstromami.com/galleries/atari800x...kb/PIC_0064.jpg http://podstromami.com/galleries/atari800x...kb/PIC_0065.jpg http://podstromami.com/galleries/atari800x...kb/PIC_0067.jpg http://podstromami.com/galleries/atari800x...kb/PIC_0068.jpg Quote Link to comment Share on other sites More sharing options...

Cartridges occupy a different address space than the OS. If they weren't soldered in, the easiest way to dump each eprom's contents would be by putting it in a eprom programmer. re-atari Quote Link to comment Share on other sites More sharing options...
1050 Posted May 9, 2009 Share Posted May 9, 2009 yes, i mean dump content of cartridge to file.. but that is internal 8kb cartridges flashed in eprom in atari.. no external cartridges. Even if the eproms contained cartridge code we still would call them eproms if they were not in their cartridge cases, so that's bad english all around. Not a problem, I can tell from the OS(s) that you are running, that English is not your native tongue so such a mistake in nomenclature is really to be expected at some point. Again not a big deal at all... Here is a BASIC program that when run with each OS should get you an eprom burn file for that OS. Which also work as emulator ROM files. The file created does not have the standard six Atari file header bytes, so those would have to be added if you were using an Atari based eprom burner. FF FF 00 00 FF 3F Would be suitable bytes to use for those Atari file header bytes. PUT equates for potential lines 22 thru 27 to do that are: 255,255,0,0,255,63 BASIC program for reading the OS ROM and saving to a file called OSIMG.ROM on Drive one. 10 OPEN #1,8,0,"D1:OSIMG.ROM" 20 POKE 54017,125 30 A=12*4096:L=4095:GOSUB 500 40 A=5*4096:L=2047:GOSUB 500 50 A=13*4096+2048:L=8192+2047:GOSUB 500 60 CLOSE #1:POKE 54017,253:END 500 FOR D=A TO A+L:PUT #1,PEEK(D):NEXT D 510 RETURN DOS needs to be loaded with BASIC before the above program will work properly. Don't forget to change the file name either in the program above or once the file has been written out to avoid having your data overwritten by a 2nd file if you use the same floppy disk to make more OS images. Be prepared for a good long wait, 132 sector file length with almost two seconds per sector written make for a long time to finish the program.
