Re: [hatari-devel] Reeking rumber analysis

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

OK, I think I know where the problem is now.
Great.

In fact, ioMemTabFalcon.c contains the following lines :


    { 0xff8240, 32       , IoMem_ReadWithoutInterception, 
VIDEL_ColorRegsWrite },           /* ST color regs */

    [...]

    { 0xff9800, 0x400, IoMem_ReadWithoutInterception, 
VIDEL_ColorRegsWrite },            /* Falcon Videl palette */



Both lines are calling VIDEL_ColorRegsWrite for the write mode which is :


/**
 * Monitor write access to ST/E color palette registers
 */
void VIDEL_ColorRegsWrite(void)
{
    videl.hostColorsSync = false;
}



So, in the both calls, videl.hostColorsSync = false (for both St palette 
write and true color palette write) and the value of the writing is not 
saved into the register (or is it ?).

There's something to fix here.

Laurent
