There's some floor flickering problems in galaxy fight neo cd version - aes is works fine thought you should have a look, its more prominent where the fighters duke it out on the space station - thanks.

[dink]

the_maq:
unfortunately the flickering can't be fixed in the neocd version of galaxy fight, basically the game is using more cycles than has for game logic in the frame before the flicker, this cuts into the sprite rendering - which ends up leaving out part of the ground sprites - thus a flicker is presented.
It works fine in aes/mvs because those machines don't have to deal with the overhead of the cd system.

On the other hand, you can fix this problem by overclocking the cpu for this game.  After loading the game / as it boots up, go to "Game -> Adjust CPU Speed", then type in "101" in the little white box.  fbn will even save this setting just for this game.

finally opa opa !!! thanks Dink Dink

Dink, I wanted to thank you for backporting the X-Men 6P changes back to MAME. If it's something that wouldn't be difficult for you, could you also please look into why the screens seem to be desynced in MAME?

In FBNeo, it's fine, but in MAME, you can see that when scrolling one of the screens seems to lag behind the other. It's particularly noticeable during the intro when its scrolling up over the planet.

[dink]

the_maq, vbt, paullogan: you're welcome - thanks for being here

paullogan: regarding the screen synchronization:
Instead of updating each screen-side every other frame as it is now, I have it update both sides every frame.  Unfortunately I'm not familiar enough with MAME's video system to implement it on their side, but it should be rather trivial to implement should you find someone able and willing to do so.

Just to inform you, the last git got damaged again, lucky i still have a backup as always. 
Appears in the scan roms option a d word instead of /roms and etc...

Hopefully the version that is currently building will fix that issue, appveyor updated the VM again so now the "previous" version has been replaced with the broken one. If that doesn't work I will downgrade it to 2017 VM and see if that fixes it

[Kev]

Although I've not tested myself should be sorted now

ColecoVision update: Controller handling re-written & added support for the Super Action & Roller Controllers
Hooked-up to the following CV games:
Destructor, Front Line, Kaboom, Slither, Super Action sports games, Super Controller Test Cart, Victory, War Games, Star Trek, Spy Hunter

The rewrite also fixed some regular controller games, such as Deep Dungeon Adventure & Sewer Sam.

Also emulated was the chip-enable wait on register writes to the SN PSG, which fixes the pitch on sounds that use the SN PSG as a PCM sample playback device.

BE (Big Endian) systems (PSP, PS3, WiiU, *anything else?*)

Anything using ppc cpu (ps3, xbox360, wiiu, wii, gamecube, older macs like G3/G4/G5, ...), and supposedly some arm based devices are big-endian too. I think psp is little endian
Not sure how many of those machines got a working port though, i know ps3/wiiu got a working fbneo port through libretro, and i think xbox360 has a standalone port written by lantus (i'm not sure he is still maintaining it though).

Just before, there was also behind the scene stuff by dink and me with savestates, from time to time they could happen on standalone but they were mainly visible with savestates based features from other ports (fightcade, libretro), such as :
- games using ym2151,ym2203,2608,2610,2612
- neogeo
- cps1
- pgm
- irem m92
- sega sys1

[dink]

Barbudreadmon, ahh yes, how can I forget.  We really did a nice job hardening the savestate system
