ComicBookDS will never work on DS-X, unless it's author implements a FAT driver.
lol thats what everyone said when dsx came out... but aparently no homebrew needed ay fatlib
dsx team said fatlib will be released tho, but its not needed (except maybe 1-2 apps that are a bit more complex)
but I think theyve done an amazing job on running fat based homebrew without the author needing to include any dsx libs
I know what I'm talking about.
The reason most of the homebrew works fine is one - they used the same registers as MagicKey 3 and therefore made DS-X instantly compatible with most od the homebrew (since the drivers for MK3 are already in Chishm's FAT library). There's no magic here.
On the other hand, ComicBookDS is using GBFS, which
has to be loaded in GBA cartridge's RAM (which doesn't exist in DS-X at all), therefore making it impossible for any slot-1 adapter to run it).
Unless the author of this app decides to use FAT instead GBFS, it will never, ever work on this device.
There's a rule, that's true most of the time. If a homebrew application is compatible with GBAmp, it's also compatible with DS-X. If it doesn't work on GBAmp, it won't work on DS-X either.
