[GameBoyAdvance] Tinygo build don't build a correct GBA ROM and execute .gba file with mgba fails: "The game crashed!"

[scraly]

Hi,

I tested to run and build the gba-display example found in this repository.

Cool, the tinygo run command is orking:

$ tinygo run -target=gameboy-advance gba-display.go
tinygo:ld.lld: warning: lld uses blx instruction, no object with architecture supporting feature detected

But unfortunately I can't build successfully the gba binary and when I test it through mgba emulator, it fails! :(

$ tinygo build -target=gameboy-advance -o bin/gba-display.gba gba-display.go 
tinygo:ld.lld: warning: lld uses blx instruction, no object with architecture supporting feature detected

$ file bin/gba-display.gba
bin/gba-display.gba: data

$ mgba bin/gba-display.gba
The game crashed!

Same things when I launch mgba in the graphical way:

So, I can't build a working gba ROM file.

$ tinygo version
tinygo version 0.19.0 darwin/amd64 (using go version go1.16.5 and LLVM version 11.0.0)

$ mgba --version
mgba 0.9.2 (f6d5f51d231053cc8a1778b7a139096d2bcf7324)

Is it possible to know how to remove the warning message and to fix the bug?

Thanks

This is no longer a problem at least with the 0.28 release coming soon. Tagging to close this issue on next release. Thanks @scraly
