FBA Development / Re: dink's FBA Development & Fixes thread

Great work on the buffered sound chips, dink! I wonder how much this will improve performances on the Raspberry Pi, and which arcade systems / drivers are concerned by those improvements. Like, will the Taito F3 benefit from this? It apparently uses ES5505 and ES5510 sound chips, but you didn't mention those.

Just a quiick question on the topic of overclocking. Could an "underclocking" option be added to Fba? Is it possible?  Mame has this option and if is useful for achieving closer to PCB levels of slowdown in some games (among others, cave shmups).
FBA does have underclocking. Not all drivers support this. It is being worked on.

Sorry about that, i didn't notice i had to set php's upload_max_filesize/post_max_size settings to 10M for this forum, it should be ok now.

Thanks! I tried to upload a file of 9.73 Mbytes (9968.83 kB) and all went well ! :)

I guess that the actual size restriction for a single file is about 2 Mbytes.

http://datasheets.chipdb.org/Hitachi/63701/HD63701V0.pdf - pg 638 has some information on resetting
http://www.gbgmv.se/dl/doc/md09/MC6809_DataSheet.pdf - and same for pg 6

Hope this is what you're looking for.

Fulg0re, for now, please rar or zip and upload the savestate to http://www.sendspace.com and paste the link.  I will try to see why attachment size is restricted - it shouldn't be.

I need you to do the test at 100% cpu, but also rename or delete neocdz.fs in config/games before running AOF 1.  This is the "Internal Memorycard"(eeprom) for NeoGeoCD, and it might be corrupted - as barbudreadmon says.  Make sure to save a backup of this file before deleting it because it has your game data in it.

best regards,
- dink

Trap15 rewrote the vblank code in Mslug2 which gives it a nice non-slowdown framerate, it's called "Metal Slug 2 Turbo" - no overclocking necessary :)


It might be related so i'll share the information : a few years ago someone reported an issue with aof3 (MVS), the issue was related to overclock and it wouldn't disappear when going back to 100% without also removing the related .fs file.
My point is that overclocking once can "corrupt" eeprom files, and it won't go back to normal if you simply set normal clock again.
Imho, setting everything to 200-250% is a mistake, i think only a few games "benefit" from overclocking (mslug2, maybe twinspri ? i don't know of any other game having severe slowdowns on original hardware), and i also prefer keeping the slowdowns of the original hardware (did you ever play the DC version of twinspri without the slowdowns ? It's fucking hard xD, i'm wondering if the slowdowns weren't there on purpose).

I cant upload the 2 Savestates. A message says that the file is to big ... It is 4 MB

That's weird... the file size restriction should be of 10 Mbytes...  :S
Restrictions: maximum total size 10240KB, maximum individual size 10240KB

[EDIT]
I did some upload tests:
file of 9,73 MB (upload failed)
file of 6,82 MB (upload failed)
file of 4,32 MB (upload failed)
file of 3,01 MB (upload failed)
file of 1,95 MB (upload successful)

I guess that the actual size restriction for a single file is about 2 Mbytes.
