One thing I really wanted to add to the Ultimate Cart was an easy way to use XEX files on the cartridge.
Thanks mainly to flashjazzcat, we've now added this as a feature to the firmware.
XEX files present on the SD card can now be browsed and launched just like cartridge/ROM files. Loading is practically instantaneous.
This firmware also replaces my original menu with the improved version by flashjazzcat. Since this is now part of the firmware, you should remove any older version of it from the SD cart (i.e. remove _BOOT.ROM if you have it).
This will become the current firmware, and I'll upload the source files to github once this has had a bit of a wider test.
I'm sure this will be a very welcome addition to the cartridge firmware, and praise and thanks should be directed to flashjazzcat who wrote the XEX loader and the improved menu - tasks both way beyond my 6502 skills!
