Thanks a lot for the releases! They surely were unexpected considering the earlier debate.

Btw, what made you decide in favor of doing so? I thought there were some legal worries in that regard, so did they go away or something?

Well, at this point Cave has ignored the roms being added to MAME (and being somewhat playable). The assumption is that they don't care.  If they/we get a c&d or a complaint we will remove the drivers from the official builds.

Found a bug on the current PGM WIP code. KOV will keep looping over and over after the character has been selected. Confirmed on a windows build too

[lantus]

fixed it

in pgm_prot.cpp use this code

Code: [Select]

static void pgm_kov_asic27_w(unsigned short offset, unsigned short data)
{
if(offset==0) {
unsigned short realkey;
realkey=ASIC27KEY>>8;
realkey|=ASIC27KEY;
data^=realkey;
ASIC27REGS[0]=data;
return;
}
if(offset==2) {
unsigned short realkey;

ASIC27KEY=data&0xff00;

realkey=ASIC27KEY>>8;
realkey|=ASIC27KEY;
data^=realkey;
ASIC27REGS[1]=data;

ASICPARAMS[ASIC27REGS[1]&0xff]=ASIC27REGS[0];
if(ASIC27REGS[1]==0xE7) {
unsigned int E0R=(ASICPARAMS[0xE7]>>12)&0xf;
E0REGS[E0R]&=0xffff;
E0REGS[E0R]|=ASIC27REGS[0]<<16;
}
if(ASIC27REGS[1]==0xE5) {
unsigned int E0R=(ASICPARAMS[0xE7]>>12)&0xf;
E0REGS[E0R]&=0xff0000;
E0REGS[E0R]|=ASIC27REGS[0];
}
ASIC27RCNT=0;
}
}

Thanks Lantus for the fix...Iv'e noticed also in the current PGM WIP code that olds, olds100 and olds100a are stuck at the calendar screen and a minor graphical bug on drgw2 and clones. Also some problem with latest ics2115.h sent by iq_132 (sounds and BGM for some games are too high, crackles and very distorded).

@Lantus, thanks for sharing the KOV fix  I appreciate it! ^^

SeeYaa!

Amazing work you guys ! and thanks a lot for porting it that fast into FBANext ^^

from what I gather, DDP2 - BeeStrom won't be playable untile the protection scheme is known or bypassed ?
Any progress on dumping gfx&snd from EspGaluda?

Drgw2 fix:

Find this (in pgm_draw.cpp)

Code: [Select]

if (xgrow) xzom = (0x10 - xzom) * 2;
if (ygrow) yzom = (0x10 - yzom) * 2;

unsigned int xzoom = (zoomtable[xzom] << 16) | zoomtable[xzom + 1];
unsigned int yzoom = (zoomtable[yzom] << 16) | zoomtable[yzom + 1];

Replace with:

Code: [Select]

if (xgrow) xzom = 0x10 - xzom;
if (ygrow) yzom = 0x10 - yzom;

unsigned int xzoom = (zoomtable[xzom*2] << 16) | zoomtable[xzom*2 + 1];
unsigned int yzoom = (zoomtable[yzom*2] << 16) | zoomtable[yzom*2 + 1];

thanks iq

fix works great. Did you take a look at kov2p yet? Its stuck on the calender screen on bootup

Might be an endian-related issue.  Try the init from the previous sources (with the different patches). I can't reproduce it on pc.

Here's a little video of Espgaluda. Thanks to Haze for sharing the dump with me.

Now we're talkin' 

Shame it was a bad dump, but much nicer than ESPKetsuda: http://www.youtube.com/watch?v=BtZT4Do00wI

Great stuff IQ! ^^ I love the video! BGM of the game is cool too!

SeeYaa!
