FBA Development / Re: FB Alpha 0.2.97.43 Bug Reports

Hi,
wofch and wofchdx will play fine: but its a weird game, you have to wait until the game starts demo play before you can start.  I think because its a CPS Changer game, so its on FreePlay mode. 

best regards,

It seems there's an input issue in Sangokushi III Gaiden: Kakou-On's Revenge DX (a hack of wofch, and its ROM name is wofchdx). This game is unplayable since START button does not work. Is it a known issue?

Hi,

it seems there is a color issue in dkong, here is the original pcb :


current mame is close to those colors, i guess it is related to this change :
Code: [Select]
0.141u2: Couriersud fixed a bug in palette_normalize_range which caused color distortion. The luminance normalization now converts r,g,b to y,u,v and normalizes y prior to converting back to r,g,b. This affects e.g. Radar Scope, Donkey Kong and Mario Bros.
fba is a lot more redish.

I'm not 100% sure but i guess it is related to one (or both) of those changes in mame :

Do you think this change is somehow appliable to fba ?

Thanks, I'll try to figure out whats going wrong with bilinear filtering.
It's alright!

Here's the ini. As I expected, the full-screen color bleeding goes away if I disable bi-linear filtering.

About the buggy tiles... Never mind, I'm stupid. They're just badly-drawn dollar bills. :\

I can't reproduce either issue - please also post your ini file so I can investigate.  I think you might be using a scaler or fx that has the bug in it (a couple are buggy and actually cause the bleeding issue which depends on the game's screen size). 

Also try with all effects disabled and let me know how it looks?
 
oops, I mean with the ending scene, I don't see what the bad tiles are in the video or in the state.  Are you talking about the money that is sorta "floating" out of his bag? :)

Here you go. Thanks for having a look.
  • cbuster_bullboss: color bleeding in full screen mode. It actually happens all the time, not just here, but that particular scene makes the problem more obvious due to the colors used. Go in full screen mode, and move your character either to the far left or far right side.
  • cbuster_ending: second punk buggy tile issue (took the save just a few seconds before the bug occurs).

About Crude Buster again, I assume the buggy tiles around the second punk in the ending scene are also a game bug rather than an emulation bug?
https://youtu.be/E6sY_sMl2aQ?t=32m11s
This bug is even in "Data East Arcade Classics" for the the Wii, but sometimes such compilations have emulation bugs, so better safe than sorry...

Also noticed I have bleeding colors on the sides of the screen when I'm in full screen mode with FBA (see screenshot). When sprites are located on the rightmost part of the screen, I get bleeding pixels on the left side, and vice versa. I guess that's just some imperfect video setting or something, rather than an actual FBA bug.

I can provide save states for both of these things, if needed.
