Hi, some time ago, i was playing Race in my PSP when I realize, that the emulator have a great GUI, but a horrible emulation :mad0::rofl:

 

 

It was terrible, slow, a incredible strong bilinear.. well, anyways, I decide to keep the gui, and rewrite most of the emulator code

 

Here is my Race version for PSP

This is the main characteristics of the emulator

 

- Most games work at perfect speed. Some NeoGeo pocket games are 30hz, and other works at 60hz, native refresh is emulated to properly emulation

- Internal database for native refresh

 

- Scaling 2x without bilinear, fullscreen, etc

- Option for screen adjustment in case of 2x bilinear (NGP have a resolution of 160x152, the PSP of 160x136)

Original NGP 2x (160x152 = 320x304)

Scaling 2x in PSP (160x136 = 320x272)

Normally the 16 lost pixels are not a big problem, but in case a game miss some important stuff, like power bar, is possible to adjust position


For example KOF R2

In this case, with a simple 2x scaling, we lost the power bar

In this case, a adjustment of 4px, will show the power and life bar, without any loss in gameplay

About hz, here is my internal database about it,


- Normally 30hz is the common refresh, and center view is perfecto for a 2x, but this games need some adjustment







This games need a perfect 30hz VSYNC
