[ZN5-MGX] pcsx4all

[lordplayer]

Una pregunta yuyoelmero, que es eso de overckloc porque no se como modificar eso, aunque aún así en mi z6 estoy satisfecho de los resultados que he logrado con este emulador

[yuyoelmero]

Overlock es incrementar la velocidad del procesador. Búscalo en wikipedía pasa que te de una definición más exacta . Pero recuerda que si haces overlock la batería se consume más rápido saludos!

[lordplayer]

pues gracias por eso aunque prefiero tener mi z6 asi ya que me gusta mas mi cel que este asi. Lo unico que me gustaria es que se encontrara la forma de poner esos juegos que no agarra el emulador como crash team racing ya que al ponnerlo se pone en pantalla negra y no pasa nada. Y descubri que con las libs que le puse para este emulador, descubri que el emulador gpsp de game boy advance es mucho mas rapido (excepto con sonido)

To speed up games, you need to get the emulator to work with recompiler. I can not do it, my knowledge of assembly language for ARM, leave much to be desired (school level). So try to contact the creators of the emulator:
Chui - sdl_gp32 (at) yahoo (dot) es
Franxis - franxism (at) gmail (dot) com
I think they both speak Spanish, and it will be easier to find common ground with them.

Here are their responses to my letter:

Hello! Can you help me with porting the emulator pcsx4all on devices running on the processor ARM11 (arm1136jf-s)?
In particular, the emulator is working through an interpreter, but the speed through a dynamic recompiler in my opinion would be higher. When you start the emulator with dynamic recompilation in gdb shows the following:

Running PCSX Version 1.9 (Feb 21, 2011).
Loading memory card mcd001.mcr
Loading memory card mcd002.mcr

It seems sys_cacheflush() is not working correctly. Please take a look on it:
.global sys_cacheflush @ void *start_addr, void *end_addr


sys_cacheflush:
mov r2, #0
#ifdef __ARM_EABI__
/* EABI version */
str r7, [sp, #-4]!
mov r7, #(__ARM_NR_cacheflush & 0xff)
orr r7, r7, #(__ARM_NR_cacheflush & 0x00ff00)

orr r7, r7, #(__ARM_NR_cacheflush & 0xff0000)
swi 0
ldr r7, [sp], #4
#else
/* OABI */
swi __ARM_NR_cacheflush
#endif
bx lr
You have to know if you are using EABI or OABI in your toolchain. And verify the __ARM_EABI__ constant is defined if you are using EABI.

Cheers.

PCSX4ALL must run OK on ARM11. I have compiled it for Android and runs on ODROID-S (ARM Cortex-A8) without problem.

About gdb trace, it is a problem with invalidate cache. You need invalidate code/text cache to work dynamic recompiler properly because it change the content of memory for cpu code. Search sys_cacheflush function at sys_cacheflush.S and try to work for your device.

I tried to fix everything that you said and got here is such a log. (attached to the letter)
Do you have any ideas?

It seems the recompiler is not generating code correctly.
I don't know to which platform are you trying to port PCSX4ALL, but you should use another compiler/toolchain.

We had problems with several toolchains trying to make it to run to WIZ/CAANOO.
For the WIZ (OABI) we use GCC 4.0.2.
For the CAANOO (EABI) we use GCC 4.1.1: Sourcery G++ Lite 2006q1-6 for ARM GNU/Linux
Take into account the recompiler is doing several ugly things to recompile the code and it has problems with some GCC versions.

Cheers.

ZN5, E8, Z6 and on any device MotoMAGX has on its board of ARM11.
Used for the assembly toolchain EABI, GCC 3.4.3 version.
I have tried to compile the new version of GCC, but it did not end with success.
Good luck!
Best Regards, EXL.

P/S Guys from this topic to connect porting too. [MENTION=15876]NestorM[/MENTION] to know how this can be corrected. I in turn will try to contact [MENTION=44726]tincho5588[/MENTION].

good info , buena info de ahi la tradusco

[Rendelor]

Version 2.3 No Oficial por rock88

Añadido soporte para imagenes comprimidas en formato EBOOT.PBP (imágenes de la PSP). Puede pasar a traves de programas como PSX2PSP o IceTea 1.3.

Ventajas
Se Ahorra espacio en la SD al ingresar las imagenes comprimidas.

Desventajas
La carga del juego tarda mas al iniciar la imagen (en general no modifica la velocidad de emulacion).

Perdon, pero alguien sabe como se llama este juego lo he estado buscando pero no se el nombre...2.png
