I was quite surprised by how slow the original driver was on Xbox hardware. M72 was the same with the R-Types running at about 18fps in-game before I took your advice and removed the scanline code.

Anything that might squeeze a few more FPS out of these games would be appreciated.  :smilie:

Porting a newer version of the V20/V30/V33+V25/V35 core.  This should fix a lot of issues and simplify driver code.
Once I get the V25 core fully working it should let us add sound to some toaplan games (Batsugun, Fixeight, Dogyuun, Grindstrm, Kbash, and Vfive).

This also makes Gussun/Risky Challenge work on M90 hardware. :)

Very nice iq. I was thinking of looking at V25 at some point - but it did put me off when I realised it required wholesale changes in the V30 core.

Vfive, batsugun, kbash, and Dogyuun now have sound. :)

The Vez cores now support a lot of new functions (getpc, runend, totalcycles, scan, etc).

All I need to do now is figure out why the tempo is so wrong for the m92 games.

That is very good news. :)

Might not be in the same ballpark, but I fixed the music tempo in Double Dragon at the weekend by holding the IRQ generated by the YM chip for longer, ie, I ran the CPU for 1000 cycles after the YM chip triggered and lowered the IRQ. That one had done my head in for a while. :)

Hmm. I'll have to pass the code over to you. Maybe you can get it going.

Anywho, I've started working on getting the rest of the toaplan(2) games added. I started with Pipi & Bibis / Whoopee!!.

Im very interested to test new drives but all links on forums are down, probably server died.Can someone upload somewhere else ?
OK i managed to find it on Barry's website.
I was wondering... did nightslashers deco32.c ported driver was included to new source or is it still unfinished ?
Dont want to be an ass but any chance iq_132 for you to port konami drivers for great beatem-ups like violent storm and metamorphic force from mystwarr.c driver ?
I guess porting midyunit.c for midway cabinets (MK,MKII,MK3,WWF) is a lot of hard work and was asked gazillion times before ?

I've been considering it, but the graphics stuff for that is big and I am unbelievably lazy.

Yes, been asked about at least a gazillion times (gazillion+1). Honestly the problem isn't about difficulty (I've dealt with more complex stuff), it's about motivation -- None of us particularly care for the MK games. :S

yeah you basically port stuff that you would like to see and thats where motivation comes from , sometimes i can spend whole night working on something then fell asleep on my chair then wake up and continue what i did but sometimes i dont have motivation to touch any coding at all.Thats life.
Maybe you could check the games, violent storm has great gameplay, best from arcade games IMO, i didnt liked the game as a kid, ive seen it in 1996 in arcades but i didnt wanted to play cause graphic looked a bit washed out i dont know...  but then i gave it a chance and its on my top list.
Metamorphic force, this one is kinda like x-men beatem-up engine but more polished and better graphics and gameplay.
You know these games work in MAME on windows PC but problem is that when FBA is being ported to new platforms like android then its great to be able to play some games which were only available on MAME long time ago but now are vailable in FBA, its more complicated to port MAME especially new builds, most ported one is with old 0.37 romset, thats even older than first MAME builds i tried on DOS long time ago.So now FBA is the one being ported with most games supported.

When I was about 6 pac land was one of my favourite games. Doesn't quite have the same appeal now. :)

Working on adding the missing games to the Kaneko16 driver. Shogun Warriors is good to go, but B. Rap Boys is still getting hung up. :(
