+Mitch Posted September 15, 2020 Share Posted September 15, 2020 I am trying to create a usable EEPROM file for the Jag diagnostic cart ROM but I am having problems finding what the correct naming convention is for it. I tried searching the forums but couldn't find anything. I am not sure if I just missed it or if the info hasn't been provided yet. Thanks, Mitch Quote Link to comment Share on other sites More sharing options...
SainT Posted September 15, 2020 Share Posted September 15, 2020 It’s just the same as the ROM image But with .e2p as the extension. Quote Link to comment Share on other sites More sharing options...

str0m Posted September 16, 2020 Share Posted September 16, 2020 Although one query, I first tried this one where I had the eerpom file with it's original name, shortened it to match the j64 file but leaving as .bin as well then also copied it to a .e2p file, this didn't work, just got the black screen when I launched the .j64 19/08/2019 19:26 2,097,152 jagdiag5394.j64 03/09/2020 19:43 128 jagdiageeprom.bin 03/09/2020 19:43 128 jagdiag5394.bin 01/01/2018 00:00 128 jagdiag5394.e2p Then in a separate folder I had just the j64 and e2p file and that worked 01/01/2018 00:00 128 jagdiag5394.e2p 19/08/2019 19:26 2,097,152 jagdiag5394.j64 Could it be a quirk/feature ( ) that having a third file name jagdiag5394 tripped it out? I can try it again last night just in case I was imagining things 1 Quote Link to comment Share on other sites More sharing options...
SainT Posted September 16, 2020 Share Posted September 16, 2020 I cant remember, but I have a feeling .bin is a runnable extension. Did it happen to load very quickly? You might find it was laoding and running the .bin file. Although I guess it should just show both files in that case with both extensions. Yeah, not entirely sure.

str0m Posted September 16, 2020 Share Posted September 16, 2020 I will try it again tonight and post back The diagnostic rom works which is the main thing, it's quite cool Quote Link to comment Share on other sites More sharing options...
str0m Posted September 16, 2020 Share Posted September 16, 2020 (edited) Ok confirmed, so if you look at my 2 folders above, One with 4 files, I select the .j64 file, it takes a few seconds to load, jag restarts, black screen for ever One with 2 files it works fine and loads the diag software So I don't think it's loading the bin fine as it takes a few seconds. I don't have a pc/card reader at home else I would try making a file with the same name of some other working rom but with .bin and see if that also stops it loading Edited September 16, 2020 by str0m 1 Quote Link to comment Share on other sites More sharing options...
