[PSP] Emulador NeoGeo pocket

Notapor theelf » Dom Feb 15, 2015 11:49 pm

Buenas,


Ya que no encontraba opcion para jugar a la neogeo pocket en mi PSP sin ningun tipo de horrible filtro bilinear, me puse las manos a la obra, y prepare este custom build de Race! para nuestras PSP

Imagen




- Lo menos importante, cambios esteticos, ajustes de screenshot, cambios de controles, boton de exit




- No mas relentizaciones y problemas de vsync. Los juegos funcionan a los fps originales

Muchos juegos de NeoGeo Pocket son a 30fps, y otros a 60fps. Todos funcionan a refresco nativo ahora

Base de datos interna para cambio automatico de refresco





- Escalado 2x sin filtro bilinear y ajuste de pantalla


La neogeo pocket tiene una resolucion de 160x152, asi que para un escalado 2x, se necesitaria una pantalla de 320x304

La PSP tiene una pantalla de 480x272, que aunque sobra horizontal, nos falta en vertical

El escalado 2x, centra la pantalla, pero en caso de que se pierda informacion, hice una base de datos interna, para ajustes de posicion

Imagen




Basicamente, el escalado 2x, seria algo asi


NeoGeo pocket Original 160x152


Imagen



PSP 320x272

Imagen




Pero en juegos donde hay perdida de informacion, la base de datos interna, ajusta la posicion


Por ejemplo, el KOF R2,

Imagen


devido a la menor resolucion de la PSP, si centramos, se pierde la barra de magia, fijarese que ya no es posible verla


Imagen



En ese caso, la base de datos interna, detecta el juego, y ajusta, para que se vea, subiendo 4 pixeles la imagen, y dejando las dos barras, la de vida y magia, cortadas, pero visibles

Como referencia de juegos


- En general todos van a 30fps, con 22 pixeles de posicion, y con perfect vsync deverian funcionar bien. Estos juegos son la exepcion


Cotton - Fantastic Night Dreams - 60fps
Bikkuriman 2000 - 60fps
Densetsu no Ogre Battle - 60fps
Mizuki Shigeru Youkai Shashin Kan - 60fps
Nige-ron-pa - 60fps
Oekaki - 60fps
Pac-Man - 60fps
Party Mail - 60fps
Picture Puzzle - 60fps
Puyo Pop - 60fps
Soreike! Hanafuda Doujyou - 60fps
Super Real Mahjong - 60fps


Rockman Battle & Fighters - 60fps + intelligent vsync + vertical = 24



Puzzle Bobble Mini - vertical = 2
Faselei! - vertical = 18
King of Fighters R-1 - vertical = 24
King of Fighters R-2 - vertical = 24
Metal Slug - 1st Mission - vertical = 16
Mezase! Kanji Ou - vertical = 8
Samurai Shodown! - Pocket Fighting Series - vertical = 16





Juegos que necesitan perfect vsync SI o SI, o presentan problemas de sincronia

Sonic The Hedgehog - Pocket Adventure
Last Blade - Beyond the Destiny




Como ultimo, esta el Gals Fighter, que basicamente va a 30fps, pero los objetos parpadean a 60fps, aun no tengo solucion, jugar a 30fps, o 60fps con vsync normal

Saludos!!

Como este miercoles viajo a argentina, y es un viaje de 32hs, mas de un dia, tenia pensado darle caña a la neogeo pocket en el avion

Asi que estuve actualizando un poco el emulador, y dejandolo mas fino. Correji tres problemas que tenia, y daban por culo


1 - Ya guarda la ruta de las roms
2 - Cuando seleccionabas un borde custom, pero no existia, se colgaba. Ahora carga el defecto
3 - Si cargabas varios bordes diferentes, se colgaba por un buffer overrun
4 - Le puse selector de idioma. Ya se puede jugar en japones si se quiere


Les dejo la descarga

This is really cool, theelf! Do you think you could contact me directly, so we can chat about your mods a bit?

Thanks for the private message, theelf.

It's nothing secret. I just didn't know if you wanted me messing up your Spanish board with English words. :D

As you may know, I was the guy that released RACE (and the original RACE-PSP that Akop improved on). Judge wrote the emulator before me, and I did a lot of work to optimize it for hanhelds (especially ARM machines). At the time, it was a goal to have a working/fast emulator on GP32 and GP2X. NeoPop, while very portable, was never very optimized.

So now, after so many years, I see that you have picked up the project and made it even better. Some things that are on my mind.

1) How portable is your code? One big problem with RACE was that it wasn't easily portable. I'd love to see a version that could be easily compiled on other systems or integrated into OpenEmu/Mednafen/etc.

2) Where can people find the latest version?

3) Is it still in development, or have you stopped working on it?

4) Have you published the source code anywhere?

Hello!

Oh, no worries about language, the important is communication.Excuse my English, is not good at all


Thanks a lot for contact me! im happy to know you, and of course, i want to say thank you for all you work. About RACE, i start modify some stuff like 2 years ago

My first idea was just remove the bi linear effect, and add a png border, but finally i fix some other small stuff, like screen position in case of 2x resolution, some small fix for games (gals fighter, SS2...)

Imagen


I can say, i just made it at my taste :)




Ok, about your questions


1 - The code I add is just normal one, nothing hardware dependent (in fact is few code)

2 - Lastest version is In this forum, but i realize the link is broken, sorry, i fix now

( I was talking about the emulator in a spanish neogeo pocket, and put some test builds, if you want to check what i was doing. Sadly only spanish
http://neogeopocket.mforos.com/1892300/11564671-juegos-de-ngp-problematicos-y-race/)

3 - If i have time, i always add something. But sadly i have no time, then i did not add nothing new since november

4 - Yes, I had the sourcecode to download for more than one year in a spanish forum called Elotrolado, and here for some months, but because i get 0 downloads in more than one year (yes, i can check this in my ftp logs), then finally i remove it, because i get tired of upload the source every time i did a binary, for nothing



About the last question, I know is the more important, sadly, right now, im not in my house in Spain.

I live in Japan and travel every month to Spain to sell Japanese games, i live one month in spain, and come back to japan. I can say i live half year in every country, then i have two computers

Sadly, the sourcecode of Race is in my PC in Spain, but right now im in japan, I will not be in spain until end of February. As soon in on spain, i will upload the source


Sorry about this, im old school, no github or this new stuff, just local files :(



Greetings, and again, i want to say thank you for your work

There is some new movement to port RACE to libretro (for RetroArch and RetroPie projects). Is it possible to get your source code? I think it is the most recent RACE project.
