[hatari-devel] Falcon emu and STE compatibility (D-Bug games)

[Laurent Sallafranque]

I did create this new function to know if I'm in Falcon mode or in STe mode.
I didn't want to add a parameter to io_mem_Init() and change the code 
everywhere.

Maybe I should ?

Or should I call IoMem_Init_FalconInSTEcompatibilityMode to set a 
"private" data in IoMem and then, use this date in ioMem_Init ?

(I prefer the second one)

Regards

Laurent
