Topic: FBA v0.2.95.23 bug fixes...

[mai]

Hi again!

I'm working on my own build of FBA (based on v0.2.95.23), trying to fix all bugs, that I've found in the project (low-pass filter problem, when "pause" has pressed, for example), and to add something new from other projects of FBA, such as Input macro-driver and so on... but recently I've found a bug, when I'd loaded a saved state for "1944 - loop master" during gameplay... and some sprites from previous frame of this game didn't dissapear, as they should, after screen redraw... that's not an emulation bug!.. but I've no idea what's wrong...

Any suggestions?..  thanks in advance...

Are you sure? Ask Jan_Klaassen about that problem. Jan_Klaassen said there are alot of problems on FBA v0.2.95.23. It not a game problem.

yes, I know, that's not a game problem... may be, some problems with codes in StatedLoad? this bug still remains in newest FBA test version, FBA Plus, FB Evolution and FBA Combo...

I've always wondered about the low-pass bug when you press pause, too. Never fixed it and thought it was pretty annoying, so I took out the low-pass feature entirely.

this is answer of Jan_Klassen:

Fixed, thanks.

about low-pass filter, just replace this code in lowpass2.cpp (don't forget to include burner.h):

Code: [Select]

//Buff[a] = (short)SATURATE(-32768, 32767, Tmp + Tmp2);
  Buff[a] = (short)SATURATE(-32768, 32767, Tmp + Tmp2)*(1-bRunPause);

and one more question:
anybody knows why mslug2 sometimes runs very slow on FBA?

[iq_132]

Mslug2 like that on a real neogeo machine. It pushes the limits of the hardware causing slowdowns.
You can fix this by overclocking the 68k, but this wouldn't be accurate.

Btw, the only bug I can think of right now is that slam masters (I think this is the one), doesn't function at all. Just a black screen.

I've heard it many times, but never seen... only on FBA... NeoRAGEx, Kawaks runs mslug2 perfect... do they overclocking 68K?..

PS yes, slammast is the main problem (but not only, some minor bugs still remains as usual in such big projects as FBA)...
PPS It seems to me, problem with slammast solved by Gangta in his FBA Combo (besides FBA Team fixed that bug in newest FBA test version)...

Most likely, yes.

Slammast wasn't broken until 95.23 (iirc), so Gangta didn't fix it in his build, it was fine then.  And yes, in the newest test it was fixed, but you asked about bugs in 95.23, not a new/test version

Its like that on Mame as well . Plus I have seen it on the real hardware .

[FerchogtX]

Mslug2 is spposed to run slow due to the excess of gfx shown at the same time, the CPU speed isn't enough for that, that's why sometimes the game runs slower, anyway is that way (certifyed too in real hardware). NRX "run" that game at the same speed, anyway you can overclock the 68K processor (as the owner of the arcades I visit XD) to increase performance... but i reccomend that in your emulator, believe me, overclocking a real Neo-Geo CPU gives fatal reactions at the end XD (almost like PUMMM!)
See ya!!!!!!
