  • I want to build my own arcade controls!
Hiya!

I am using the latest CRT Emudriver with a 6450 and win7/x64 but when I try to install the GBA resolution from user-modes.ini

Code: [Select]
## Game Boy Advance ##

 240 x 160 @ 59.730000 gba

it gets cut or something... I have appended user-modes after the super-resolutions ini , other modes get installed fine but this one keeps getting rejected.
I also tried to edit a 160x144 resolution for the original GameBoy but it gets rejected too. I tried 320x288 and it only gets installed with 52hz refresh rate.

Is there a solution for these issues? TIA for any info/help!

Edit monitor.ini files. Just change value 192 with 160 in appropriate monitor type for example:

From:

monitor "arcade_15", "Arcade 15.7 kHz - standard resolution", "4:3"
        crt_range0 15625-16200, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 288, 448, 576

To

monitor "arcade_15", "Arcade 15.7 kHz - standard resolution", "4:3"
        crt_range0 15625-16200, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 160, 288, 448, 576


As for 160x144 use 320x144 or 320x240 but enable integer stretching in emulator and/or keep aspect ratio. Of course You need edit monitor ini for this mode again.

^ thanks haynor666, I'll report back tomorrow but I am sure all will be good  ;D

the info came just in time, I started working seriously in my cab... it's no astrocity but it will serve as well as it did 28 years ago  :D (still a WIP , there is stuff missing and stuff that needs modifications/replacement ... most annoying is the wait time for the joystick shaft extensions)

well the INI editing worked, the results are not good  :D
160x144 if set in VBA-M just crashes the pc, BGB can't even use it... 240x160 is selectable and working but it resembles the 16:9 mode on a 4:3 screen , it doesn't seem to be a VBA-M issue it's just the way the resolution is displayed...

Don't try put 160x144 in system. 240 vertical lines is limit in system. Use doubled 160x144 -> 320x144. If this not working then use 320x192 or 320x160.

If you need proper aspect ratio (nice square) use 264x240 or 256x240. It's impossible to display GBA or GBC screen on full TV/arcade monitor area without stretching or pixel doubling. The  only option will use monitor/TV service menu to manually stretch picture.

Generally 144 lines in system is not possible so groovymame is using 240p mode and limits active lines to 160. You will have black bars on upper and lower parts of screen. The same goes to all 192p and 224p modes.

sadly none of these resolutions display satisfactory in my setup, I believe it's the 6450's fault because both the arcade monitor and a  Commodore 1084 have the same issue: these modes display like a 16:9 mode on a 4:3 tube... maybe one needs to adjust the V.Size but I am not prepared to do that and mess with the other resolutions... I guess I can live with that  :lol
Thanks for the help haynor666!

Of course it will look like 16:9, that's why I suggested 256x240 or 264x240. It's impossible without messing with monitor/TV geometry to get 144 or 160 lines filled whole screen.

I'm using for VBA-M 240x240 and I'm stretch TV picture in service menu to get proper aspect. For GBC the best way for me would be 264x240. Games won't be on whole screen but at least You get proper aspect ratio for GBC screen.

ah, that clears things up - thanks for the info  :applaud:
I ended up using some interlaced resolution - can't remember atm which one - but it looks square-ish and covers most of the screen ... not optimal but on the other hand on a 25" tube I don't think gb/gbc would shine ... I am pleased since I don't have to mess any dials for other games so I just called it a day  ::)

To

I also changed the 192 to 160

but every time I create modes in vmmaker, it just makes 240x192 and that's the only resolution in vba-m :-\

Any ideas?
