Title: Groovymame 384x224
Post by: dynamic_duo on June 01, 2019, 04:18:06 pm

Hi,

I want to know how to set Groovymame v0.209 to have the native resolution of the system
CPS1 384x224,  the one that is currently displayed is 384x240.

I have the same thing for CPS2 / 3, on the other hand on NEOGEO it's ok.


System :

- CRT TV RGB
- Windows 7 64bits
- ATI Radeon HD5450 1GB "bios flashed 15khz"
- CRT Emudriver & CRT Tools 2.0 Beta 15 (Catalyst 12.6) for Windows 7/8/10 64-bit

Thanks

I feel like a pinned thread with a FAQ is due.

Technically 384x224 (224 active lines) is possible but picture geometry will be the same as 384x240. Since neo geo is 320x224 all systems will have to use 240 lines.

Like donluca suggested - read the FAQ.

There's no FAQ.

Does anyone want to take up the task and make a FAQ thread? And of course keep it updated with the questions which cyclically come over and over again.

I could always search! ^^


to sump up:

for a 384x224 game, when rendered to a resolution of 384x240, DirectDraw will leave the appropriate black
edges up and down, while Direct3D will stretch the pitch to 240 lines.

finally the best rendering is 384x240.

Thanks all for reply.

That's outdated information. Direct3D will also leave the required borders (as long as integer scaling is applied).

Ah ..

so it's better to have a native resolution.

???

240p = 224p (for cps1)
