There is a GBA version of Desert Strike.
Don't forget to check Dreamkatcha's Monster list of Amiga game remakes/tributes/clones
for GBA/DS entries.
As you can see in the thread I have suggested some homebrews for the list, if you know other Amiga-inspired ones not yet in the list, please mention them.
Speaking of which, Alekmaul has written, among other things, an emulator for the arcade version of Klax
, so why bother with the MegaDrive version (never tried the GBA version so I can't give a comparison).
