Hi, I'm working on a movie player for GBA and I want to exit to the normal SC initial menu, how can I do this?

Good question... sorry I dont know. Is there a way to do a hard reset from software wrather than just a soft reset?

the supercard patcher can make it on GBA games.. so there is a way..

maybe  some one with proper skillz like Bubble4k can look what the patcher do with the room!

Hi, I'm working on a movie player for GBA and I want to exit to the normal SC initial menu, how can I do this?

The only way i could think right now is write a small asm routine that jump and execute the first byte of the supercard firmware.

thanks for the tips, I'm going to check a few things

welll, I can say that SWI calls doesn't work, i tried a hard reset (SWI 0x26) and a I get  an assert from int.c telling me that the interruption is not assigned to a function, i supose that the SC is sending this message....
also tried a soft reset with the same result... I'm still working on this (well, at last it's funny XD)

the movie player for GBA is almost finished, only little A/V sync issues after 5-6 mins playing, but maximum delay is 1s

I might be wrong, but the SC seems to do a soft-reset on L+R+select+start.

That is, SWI 0.

When I tried a hard reset, also tried the soft one (because changing the number isn't a hard task ), and the result is the same, assert at int.c, so maybe it has some kind of interrupt reload to make this work or a separate implementation of the soft reset interrupt function.

I think you're right, if it calls a hard reset, the nintendo logo should appear annoying users each time , so a soft one is preferred, I'm going to make some tests separately, maybe it's a HAM related issue, so I'm gonna test it outside HAM

are you using c? did try you using an assembly block to execute the SWI?

Something like

asm
{
 swi $0000
}

[wurlde]

I'm using assembly embedded in C with
asm volatile("swi 0xNN" ::: "r0","r1","r2","r3");
(I'm writting this recalling my memory, maybe some thing is missed or missplaced, now I'm at work and I don't have access to the code)

where NN are the number of the interrupt(0 or 26), the rest of the sentence is used to avoid register corruption if I'm not wrong

I can confirm that it's not a HAM related issue, i tried the code above alone and it worked on emulator and flashcard, but not in SC
