"Together me and barbudreadmon found and fixed some more crash issues in a few games with -O3 (high optimization) with later versions of gcc.  It turns out that vectorized/simd operations need 32bit integers to be aligned on a 4byte boundary.  Because of this, FBAlpha will run much better on Raspberry Pi and other smaller/embedded systems.  Note: barbudreadmon did mostly all of the hard work here, so big thanks! "


Excellent work from both

This is the 3rd of 4th attempt at fixing this - and this time was finally a success!  ...So I'm really happy to bring this news:
Xain'd Sleena is working perfectly now.  2 deadlocks and a bunch of flickering sprites are gone :)
EDIT: ...a couple hours have passed since this post... To be sure the new fixes hold up, I playtested the game all the way to the end, and its quite awesome.  especially that last level when all the prior bosses start chasing you through the level to your spaceship as their planet is rigged to blow up.  wow, what a rush :)  Did I mention that I was super happy that this game is now perfect in FBAlpha?  Hopefully we can have a release soon.

best regards,
- dink

If I'm not wrong, the attached screens should be grabbed from second stage... I played until the third stage and the game seems to work properly.
Are you able to create a savestate just before the game freezes?

Hi, Willowar - I think I know the problem with Super-X.  Are you using a keyboard?  Can you try using a Joystick or gamepad instead?

thanks,

The game seems to freeze when you push up and down at the same time... logically this can happen when you use keyboard controls (as dink pointed out); with a pad or a stick it's impossible to press up and down at the same time...

On a side note :
Just remembered some guy years ago who won a mario kart championship because his controller was in such a bad shape he was able to press left and right at the same time (shifting left and right rapidly while drifting enable turbo boost in many mario kart).
So it's actually possible to press opposite directions with a pad in a bad shape, or modded, because of course some people modded their controllers following this story :p.

... a symbolic case, when a defect becomes a merit! :P

Moreover you could map the joypad buttons as directional inputs... so you would be able to press all directions at the same time!  :biggrin:

Fixed a shedload of driver-bugs, big thanks to gab75, Pityesz and WILOWAR for reporting!

Wall Crash - fixed paddle inputs / default settings
Taito's Operation Wolf 3: automatically use default gun calibrations on first boot
The Karate Tournament: missing button #2 and sprite:tile offset glitch
Quartet, Quartet 2: cracking/popping noises from the dac have been quenched.

best regards,

Operation Wolf 3-day (in the slapshot driver)

To get the graphics right, I set up a priority bitmap between the TC0480 (Taito tilemap chip) and the Taito F2 sprites code.

Now the sprites/objects priority is almost perfect! Thanks! :)

I'm hoping you named those incorrectly. The second one is definitely worse. ^^

Really... you are too strict! :P The second screenshot is not worse! There's only a "priority issue" with the truck and the tubulars...
in the first one the enemy soldier and the civilian seem to be inside the barrels! :P

OOps, you're right, the tubes on the left side definitely should be infront of the truck, investigating..
