Could you please be a bit more specific? By what you said, I understood you:
- Started SofaRun;
- Saw the welcome screen (the one which says to press joypad/joystick button A, Return or Space key);
- The screen went blank without any interaction from you;
- While it was blank you pressed Return;
- It showed that a file was unzipping.
I have three questions:
- Did I understand what happened correctly?
- What was the file that was unzipped?
- What happened after unzipping the file? Did it show something on the screen? Did it freeze? Did it crash? Did it go back to DOS?
I hope we can get to the bottom of this. 
Hi Louthrax,
JoySNES seems works properly now.
Ah, good news, but I'm still not sure why it works
In fact, it still doesn't work and sorry because I had not had time to report it and then I forgot.
I delved a bit into Sofarun and found the following joystick routine.
0476: ld a,#0f ; <- useless code 0478: out (#a0),a ; <- and that interferes 047A: ld a,d ; <- with the 047B: out (#a1),a ; <- JoySNES 047D: ld a,#0f 047F: out (#a0),a 0481: ld a,e 0482: out (#a1),a 0484: ld a,#0e 0486: out (#a0),a 0488: in a,(#a2) 048A: or #c0 048C: ld l,a 048D: or #f0 048F: cp #f0 0491: ld a,l 0492: ret nz 0493: or #0f 0495: ret
This routine is incorrect. It prevents also the use of the code key.
So I replaced that by the following routine:
0476: nop 0477: nop 0478: nop 0479: ld a,0Fh 047B: out (0A0h),a 047D: in a,(0A2h) ; <- To fix 047F: and 080h ; <- the 0481: or e ; <- code key 0482: out (#a1),a 0484: ld a,#0e 0486: out (#a0),a 0488: in a,(#a2) 048A: or #c0 048C: ld l,a 048D: or #f0 048F: cp #f0 0491: ld a,l 0492: ret nz 0493: or #0f 0495: ret
I also replaced:
58D4: ld de,#938f 58D7: call #0476 58DA: push af 58DB: ld de,#eccf 58DE: call #0476
by:
58D4: ld de,#930F ; You can replace it by ld e,#0F 58D7: call #0479 58DA: push af 58DB: ld de,#ec4F ; You can replace it by ld e,#4F 58DE: call #0479
Thereby my JoySNES and the Code key now works well.
