Hi,
I start some tests to create a game on NeoGeo CD and before starting the development, I wish to test specific hardware features.

I can play CD audio wav files (in raine emulator) and the graphic part works too.

I wish to load all sprites at the beginning and only load a different .SPR for the background every level.

In the "IPL.TXT" I have a demo.spr (135ko) and demo2.spr (35ko). I wish to put the second file in the start of the bank 3 (name, num bank, start offset of the bank) but the NeoGeoCd doesn't like it and show me an error message DISC I/O error ID = 0000
Without the line demo2.spr,3,0, the game run but with a blank square instead of the sprite (because it didn't load)

DEMO.FIX,0,0
DEMO.Z80,0,0
DEMO.PCM,0,0
DEMO.SPR,0,0
DEMO2.SPR,3,0
TEST.PRG,0,0

I use buildchar file to create demo.spr :

<?xml version="1.0" encoding="UTF-8"?>
<chardata>
  <setup>
    <starting_tile>256</starting_tile>
    <charfile>out\char.bin</charfile>
    <mapfile>out\charMaps.s</mapfile>
    <palfile>out\charPals.s</palfile>
    <incfile>out\charInclude.h</incfile>
    <incprefix>../</incprefix>
  </setup>
  <pict id="monstre">    <file>gfx\monstre.png</file>    <flips>xyz</flips>  </pict>
  <pict id="bg_001">    <file>gfx\lb2.png</file>  </pict>
  <pict id="girl3">    <file>gfx\girl_3.png</file>    <flips>xyz</flips>  </pict>  
</chardata>

and demo2.spr :

<?xml version="1.0" encoding="UTF-8"?>
<chardata>
  <setup>
    <starting_tile>0</starting_tile>
    <charfile>out\char2.bin</charfile>
    <mapfile>out\charMaps2.s</mapfile>
    <palfile>out\charPals2.s</palfile>
    <incfile>out\charInclude2.h</incfile>
    <incprefix>../</incprefix>
  </setup>
  <pict id="girl4">    <file>gfx\girl_4.png</file>    <flips>xyz</flips>  </pict>
</chardata>
