How does this look?    (second picture is how it looked before)

Waah, it looks accurate according to flyers around : http://www.flyerfever.com/post/93471170263/aqua-jack
Good job again dink!

Nice fix @dink proper correct colours now in Aqua Jack for the first time in any Emulator.

We're not out of the dark yet, the colors in level 4 of Aquajack are messed up, but can't be un-messed up at this point by shuffling data around - but I have another idea that I'm going to explore tonight

given that the old colours also look 'ok' (hence nobody noticing they were wrong) I'd suspect it's some kind of pen addition effect, and that maybe both are valid and the game at some point does a 'time of day' effect.

Bad news regarding Aquajack color hack:
Unfortunately its not possible to get all levels to look OK without some rather severe and ugly palette hacks.  I've decided to just leave it as-is/as it was for now until the problem is a bit better understood.  Who knows

While fixing some default controls in fbalpha-libretro i ended up searching for information on the Chase HQ cabinet :
http://www.ukvac.com/forum/taito-chase-hq-fix-tidy-up_topic357660_post994952.html

I'm not 100% sure but it seems to me like the gear is supposed to be some kind of analog control, or at least something with 2 positions. Someone on github also mentioned mame is handling it as an analog control.

Controls in fba look like this :

Code: Select

A("Steering"         , BIT_ANALOG_REL, &TaitoAnalogPort0     , "p1 x-axis" ),
{"Brake"             , BIT_DIGITAL   , TC0220IOCInputPort0 + 5, "p1 fire 1" },
{"Accelerate"        , BIT_DIGITAL   , TC0220IOCInputPort1 + 5, "p1 fire 2" },
{"Turbo"             , BIT_DIGITAL   , TC0220IOCInputPort1 + 0, "p1 fire 3" },
{"Gear"              , BIT_DIGITAL   , TC0220IOCInputPort1 + 4, "p1 fire 4" },

Edit : another issue with controls : p2 coin in backfire doesn't seem to work.

[dink]

barbudreadmon: some games have analog or digital controls, and sometimes we chose to go with the digital control only because it was easier to code in.   Tonight when I have more time I'll check to see if this digital control is somehow impeeding gameplay, and if it is I'll add the analog control.

Regarding Backfire, p2 doesn't work properly in any emulated environment.  I added a single-screen setting for this game a few days ago.  (Wrally2 also has this option, avail. in next version - but both 1p and 2p work)

If i understand well, the Gear control had 2 positions (High and Low : https://www.arcade-museum.com/game_detail.php?game_id=7318), so i'm actually just wondering how the current fba controls handle it : Gear button pressed is High and unpressed is Low ? That would be totally fine, having analog control while the control only support 2 positions seems kinda overboard anyway.

Now I remember!
Chase HQ's gear shifter uses the new burn_shift device, when the gear button is pressed it toggles between high and low gear, and also writes a little H / L to the bottom right of the screen.  It was added in .40.

Thanks for the explanation .

I noticed what appeared as some kind of graphical glitch on "VS Block Breaker" title screen while fixing libretro-fbalpha's default mapping. Didn't check on fba standalone yet though, i'll try to confirm and make a proper report with a screenshot when i get back from work.

[dink]

barbudreadmon, try deleting the nvram / config/games/vblok*.fs, I think that might help in some instances of weirdness with vblokbrk, but if there is still an issue please let me know,

This one almost drove me crazy as i wasn't able to reproduce it and was starting to wonder if i dreamed it, but i was finally able to reproduce it.

It is not a nvram issue (got it before and after deleting my nvram), but it only happens if you insert coin at a specific time (see my second screenshot).

I don't think it is worth investigating, as it doesn't seem to impair gameplay.

Edit : the screenshots are from fbalpha-libretro but i'm able to reproduce it on fba standalone : just press coin button during the sfx after my second screenshot

[dink]

barbudreadmon, thanks for the reproduce, I've been trying to track down the cause of that one for ages

Hi everyone,

I think those games have some input issues :
- deroon/deroona : button 1-4 doesn't seem to do anything, both in menu and in game
- lordgun : i couldn't find a way to reload, i suppose it makes sense since i can't shoot out of the screen.
- most of the "hunting" series (deer, trophy and turkey) seems to have issues with the shot not following the crosshair.

PS : to be honest, i'm mostly interested in deroon, since puzzle game is one of my favorite genre .
