Hello,

me too i starting game developpment on neogeo pocket color  

actually i using assembler : ASM900 (toshiba assembler) it worls well.
but i would like use now C compiler, for large project it's better !

i have follow your tutorial
https://ahchayblog.wordpress.com/2018/02/19/baby-steps/ on your blog

when i try make, this is the error

cc900 -c -O3 main.c -o main.rel
TLCS-900 C-Compiler (32)  Version 4.23
Copyright© TOSHIBA CORPORATION 1994-1997  All rights reserved

cc900-Fatal-116: cannot execute "G:\NGPC\t900\bin\thc1"
make: *** [main.rel] Error 3



have you seen this error ?
what is THC1 ? is used by CC900...
i'm running under windows7 64bits


of course : THC1.EXE exist  on my path : G:\NGPC\t900\bin

Replace the T900 folder with this one.

it works !


Thanks very much

Yes, I should probably mention that - thanks Shicky. It works best if you take the original T900 folder and add in the contents of the new one.

i currently looking K2GE (color chip) regsiters using documentations


everything is well documented except for :


8100->8107    : Sprite Palette Table (Mono, 2 x 4 entry palettes (Shade = bit 0-2 of byte))
8108->810F    : Scroll 1 Palette Table (Mono, 2 x 4 entry palettes (Shade = bit 0-2 of byte))
8110->8117    : Scroll 2 Palette Table (Mono, 2 x 4 entry palettes (Shade = bit 0-2 of byte))

i dont understand yet what is meaning.
8 bytes , and for each byte only 2 bits used.


because Color palette is already defined on :
8200->827F    : Sprite Palette Table (64max)
8280->82FF    : Scroll 1 Palette Table (64max)
8300->837F    : Scroll 2 Palette Table (64max)


on some documentations a see :
8100  palette LUT for sprites   (LUT : LookUpTable)
8108  palette LUT Scroll 1
8110  palette LUT Scroll 2

Hi,

0x8100 to 0x8117 are for the B&W NeoGeo Pocket (K1GE). It's similar to the color version, it defines transparancy + 3 shades of grey instead of RGB color.

If you intend to develop for the color version, you don't need them.

Loïc.
