Hello guys and girls
Hello Rugxulo

Can anyone tell me if this function has an error?=20
the compiler says "Can't find a register in class DREG while reloading 'asm=
'" and highlights the word 'asm' in the code

i succeded with the linear framebuffer but my game still runs slow under DO=
SBox, ...... now i'm trying the protected mode bank switching

this is a part from what i stole from the DJGPP page about VBE 2.0

what i suposse -and hope- is that there is no error in the function and the=
re is no assembler in my compiler

Thank you
