Thanks for the quick reply,

Is the entire alphabet included or only the ones used by Sega, for instance when i did some programming for cheap japanese handheld ports, they only included letters used,

A E I O U 1 2 3 4 5 6 7 8 9 0
N M . , :

That was the format for the file.

Edit "E" in twice XD

Thanks, would you recommend me looking at the ASM output by the C conversion. say if i write some simple print routines in C and then look at the output ? or would it be too in depth because its gonna be too messy? sorry Steph not insulting your Dev kit. :D

@Tomaitheous, what is the font used for "Produced by or under licensed by Sega enterprise" at startup. i understand that its stored in the hardware but would it be possible to call it?

also how would i use it? would i call it like a header file?

Thanks again guys.

no errors so far now. BTST is very handy.

it doesnt seem to like $1, $2 when defined so i changed them to num1, num2.

as for the actual VDP, this is where i get a bit sketchy.

does the font already exist or is that included when compiling?

sorry for noobness. ASM aint easy XD

Ah my mistake thanks for the correction.

how big would these EEPROMS be ? as big as the ones in the full megadrive carts?

if i used it, would the PCB have to fit in an extended cartridge like Skitchin'
or jungle strike. they are considerably bigger than say sonic 2 for example

Many thanks

for some reason no errors appear in several ...
