FBA Development / Re: FB Alpha 0.2.97.43 Bug Reports
« Last post by iq_132 on Today at 09:18:29 am »
Treble Winner,
I've been wanting to fix the chiki one for ages, but forgot about it actually.  I verified that they both happen in past versions.  chiki since I've been with the project.  Captcomm always did the raster a bit wrong, but didn't write the weird character above until around the time of the new m68k core.  You probably didn't notice the problems because they only happen for a frame or 2 during raster effects (scroll register hackery) by the game.

chiki/captcomm actually run at 262 lines (which can be verified in the emulator encyclopedia aka MAME), having it at 259 previously was basically running vbl at the wrong line.  secondly, drawing after vblank is bad for any raster effect.
Explanation: after vbl and until line 16, the game prepares some the next scene / scroll registers / etc.  The reason for the glitches is simple, the game was drawing during the preparation of the next scene.

best regards,

Can confirm:
MCFG_SCREEN_RAW_PARAMS(XTAL(16000000)/2, 512, 64, 448, 262, 16, 240)

That should also put our fps to 59.637404580152671755725190839695 hz ^^
(1600000/2/512/262)

Bonky0013, problem with captcomm also fixed :) thanks!
note to others; the problem happens while the Captain Commando text is being displayed with a raster effect.

Did these bugs happen in older versions as well? The fixes are hacky at best and indicate a problem with our timing which probably needs further investigation. Especially if they worked fine in previous versions.

Bonky0013, thanks.  chiki video glitches are fixed :)

re: captcomm
I can't reproduce this problem.  is the romset OK?  how about CPU speed - is it at 100%? (Game -> Reset CPU speed to 100%)
will you post your config/games/captcomm.ini file?

EDIT I found the problem!

Hi ^^

In first, i want to thank you for all your work  :wink:

I don't know if those "bugs" are know issue, lot of time i do post it.
They're on Cps_1.

Captain commando : On the title screen appears, look on  I of CAPTAIN.

Chiki Chiki boys : The screen titles appears and disappears the time of one frame (i think).
Similar for the screens of the demo.


Not a bug, just an information ^^

For the B_18 PPU ID, i have see it's not matching mame on ctrl, pal ctrl and layers enable. (i have game converted on B_18 for my personnal use.).
I have looked on it because all my conversion are black screen :)

After created another B_18 (matching mame), my conversions works well, but i have break sf2ue and sfee (only this 2 games work on b_18)
Need more look for me on the code for understand ;) :)

Best Regards from france :)
And sorry for my limited english  :redface:
