As I wrote in the "FBA Discussion" section, I checked all "Rohga Armor Force" ROMs (obviously with the latest FBA release) and the drums sound effects seem to be missing...

Sorry for the double post. I will continue in the FBA Discussion.

There are an another bug with the Shadow Force every version. It crash with this error:

Guru Meditation #C0000005.00911EB6

I checked all three "Shadow Force" versions (shadfrce, shadfrcej, shadfrcejv2) and they seem to work fine... I used FBA 0.2.97.37 32 bit, with basic and enhanced blitter. You can try to change the video settings and delete the related "shadfrce*.ini" files (*/config/games).

PS: truth be honest, I made a quick test, then I can't know if the game crashes during an advanced stage.

Now as you say it really not happen anywhere in the game. It only occurs in the Scientific Laboratory stage, when the bridge collapse under you and you fall down. But it occurs every time I tried no matter how I set up the video settings.

[dink]

Please give me a savestate from right before it crashes, so I can debug it and fix it.
p.s. use the exe I pm'd you, as it contains a few fixes for shadow force from earlier this month and I can't debug older savestates.

thanks,
- dink

[Pityesz]

I used the new .exe you send, the crash still occurs with "Shadow Force (US, Version 2)". I didn't tried it with other versions. Here is the save state and the log files attached to this post.

The save state is right before the crash. You just need to walk forward till the bridge break under you.

[dink]

Thanks!  I will debug the issue when I get home (I'll be away for a day or 2 yet and without a compiler).

Some good news/progress on the Megadrive driver that I did before I left:
The Chaos Engine, Outrunners, Sonic 3d and a few others runs perfectly now - it took days of debugging and re-writing before I could get it working right.  There was a few times where I thought it would be impossible to ever get them working right together.    A fix for one game would break the other, and so on.   A big part of the problem is the fact that each frame can vary on cycles/total cycles due to dma transfers stealing cycles from the processor, and the BurnTimer system is a bit finicky in this situation. 

[Pityesz]

Oh that's right! Merry Christmas! 

You're welcome. I look forward to the new version. I hope the Wolf Fang's drum will be fixed too. 

[dink]

Happy New Year everyone!

Been working nonstop on Megadrive, doing MD/Genesis research and so forth (for some reason it is really -addictively- interesting for me)

Fixed a ton of timing-related graphical quirks in the past couple days, added some vdp fixes/tricks and tonight I found a solution to a sound issue that has been bugging me (literally) for quite some time now - it was a 2 part fix - the irq's needed to be latched instead of held high for a line which fixed lost notes/too fast/too slow music during heavy video activity.  The second part was that we weren't carrying over the end of frame z80 cycle count, so every 60 frames or so, we running 1 scanline too many worth of z80 time on average.  The games which were affected the most by this are Williams Arcade Greatest Hits: the dac would get mucked up or disappear altogether in Sinistar and Doom Troopers: level 2's awesome music would drop notes or run too fast for a second or so every once in a while or when there was heavy player/screen movement. EDIT: also, Battle Squadron no longer requires a special fix/hack for the music

[and now for a bit of a rant that has nothing to do with FBA]

The Genesis/MD holds a special place in my nostalgia, because for me it was the last console to offer games that suits my generation / style.  I'll admit I'm a bit old-fasioned, but after the demise of this system sometime in the mid 90's, I had totally given up on games until late 2011.  Sure, there was a few good 2d game releases peppered in here and there in later consoles, but it was never the same.

that's it for now,
best regards,

Do you by chance mean Tecmo's Wild Fang?  If thats the case, the drums are working fine in the latest FBA - they're louder/more prominent than in MAME anyways.

Happy New Year everyone!

Happy New Year to you too... and to the other forum users!

Thanks a lot for your work... now the megadrive emulation is really improved !

No, I mean Data East's Wolf Fang (or Rohga: Armor Force). The game alongside with Vapor Trail and Skull Fang on Arcade.

No, I mean Data East's Wolf Fang (or Rohga: Armor Force). The game alongside with Vapor Trail and Skull Fang on Arcade.

For an easier identification, the zipnames of main ROM and clones are: rohga, rohga1, rohga2, rohgah, rohgau and wolffang.

Happy new year 

[dink]

Thanks, sometimes I get confused
EDIT: Wild Fang / Rohga is fixed now.
