Feature request: TGX file extension

[Dinierto]

This extension is supported in software emulators but not in the core.

If you rename them to .pce or .bin do they work normally? Mostly asking in case this format is some old interleaved format from old dumpers.

I don't really see the point.
It would appear to be a way to cause confusion among users, as I assume some of these ROMs would be bit-swapped whereas others may not be.

Plus, it would seem to legitimize new sources of potentially bad rips (many of the older rips were unreliable, and had inconsistent suffixes). I've also given up on trying to keep track of TG rips by CRC, since the startup code may or may not be patched to disable it, and there is more than one way to patch these to disable the startup code.
