Again a new version : 0.93b

I needed to fix some stupid issues, here's the complete changes log :

* Fixed a stupid bug in deprecated memory functions.
* Added Bitmap structure for easier bitmap manipulation (created from .bmp resources).
* Modified Plan A & Plan B location in VRAM.
* Added methods to modify Plan A, Plan B, Window, Sprites list and H Scroll table in VRAM.
Note that doing that you may have troubles with SGDK methods which use hardwired locations.
* VDP_setSpritesDirect(..) method so you can now senn a SpriteDef array buffer directly to the VDP.
* Handle a new resource type : WAVPCM (.wavpcm)
The file file is transformed to adpcm data and can be played directly from the 2 channels ADPCM driver.
Note that WAV sample rate should be at least equals to 22050 Hz.
* Fixed a bug in bintos tool.
* New wavtoraw tool, source is provided.
* Added tools sources.

Does SGDK help in any way with battery backed ram? To have save games?

With the last update, yes.

You can read this thread to learn more about savegame

Weird behavior using SGDK last version and Widnows7: depending on the .wav source, wavtoraw.exe, generates 0 byte files, huge files or infinite loops.

It seems there's an error in sram_a.s file

file is

Code: Select all

SRAM_readWord:
    move.l  4(%sp),d1
    add.l   %d1,%d1
    lea     0x200001,%a0
    lea     (%a0,%d1.l),%a0
    moveq   #0,%d0
    movep.w 0(%a0),%d0
    rts

think it should be

Code: Select all

SRAM_readWord:
    move.l  4(%sp),%d1<--------------------% is forgotten
    add.l   %d1,%d1
    lea     0x200001,%a0
    lea     (%a0,%d1.l),%a0
    moveq   #0,%d0
    movep.w 0(%a0),%d0
    rts

If one of the assembler flags is --register-prefix-optional, then it's fine... they could all be left off.

When i compile with SGDK & code blocks, this return me error when without %

To say the truth, i don't know how to configure the assembler so it was more easier for me to add the % symbol

I have to fix that that

Have you some simple wav files leading to these problems ? I rewrote the tool so i am (unfortunately) not too surprised to hear about bugs...

oofwill> Oh you're right, i don't understand GCC did not complained about it during compilation
