Gowin gb/gbc games on GBA: no sound

[prince tomato]

hi guys,

i am fiddling around with some Gowin games on my consolized GBA, to get around the fact that some of these apparently only play on original dmg or gbc, and not on GBA.

here is what works:

SNES=> Pro Action Reply=> Jap Super Gameboy II,
looks like a gb game with the added colours of the super gameboy.

GBA=> GB Sacker cheat device= full colour, but no sound.
strange thing: the Gowin games that DO work directly on GBA without any extra stuff will NOT boot on GBA with the cheat device, only when inserted directly.

have any of you experimented with this before?
does anyone know of another way of playing GBC games on a TV? (without emulation)

any hints or tips are more than welcome.
