Custom Firmware 2.2 cannot add OPK files - Unsuppported Format

[neil74]

Has anybody managed to add a new OPK beyond the ones bundled with CGW 2.2?

I have tried to add amongst others vice (C64), uae4all, genplus, genplusgx and mame4all and for every one I get an unsupported format error.

Am I missing a trick here?

Are you using the right OPK files - made for the RG300?
If you're trying to use the RG350 emulators it won't quite work. Since they're using different boards and versions of OpenDinguX, there's lots of little dependencies and other inconsistencies that will cause errors (its not like a Windows PC wherein many things are universal/standardized making mass installation easy).

Unfortunately the RG300 isn't as well documented as its successor, so your best bet might be to ask around in the communities that develop the firmware for these devices, you can find a multitude of links (discord, etc.) here: https://www.rghandhelds.com/

For good measure, here's the github for RetroFW as well: https://github.com/retrofw/retrofw.github.io/wiki/Install-Firmware

Thanks, I guess the opks were probably 350 not 300.
I'll check out those links
