GpSP

Revision as of 20:06, 1 December 2011

Game Boy handheld

gpSP (game play SP) is a Game Boy Advance emulator, made by Exophase, for use with the Sony PlayStation Portable and GP2X video game systems. There have been ports to iPod the iOS, Maemo, Symbian and many others.

The PSP version runs most commercial games at full speed, however some still have problems from minor or severe glitches, while others are very slow. The GP2X version is similar to the PSP one, but typically slower. Unlike VisualBoyAdvance, which high-level emulates the GBA BIOS, gpSP requires a GBA BIOS file in order to operate. Due to copyright reasons, this BIOS cannot be included with the emulator by Exophase, and users must dump it on their own using a Game Boy Advance flash cartridge. Some games do not need the BIOS file to play, however most do.

To date, gpSP has proven to be the most efficient, compatible and widely used of all GBA emulators for the PSP, GP2X.

Exophase has stopped working on the PSP version of GpSP, in favor of the GP2X and Pandora versions of gpSP. Future versions of gpSP will be closed source due to the constant third-party re-release of gpSP against Exophase's wishes.

Installation

gpSP for Maemo is already avaiable on Maemo Repositories,

What means you can eighter use your favourite app manager to install it, or go through the following command on xterminal.:

apt-get update
apt-get install gpspmgui

How to uninstall

If you wish to uninstall gpSP from your phone, simply use

app manager.

And that should uninstall gpSP from your device

How to run

Simply use the icon ! Enjoy your games!

Make sure you have a copy of a gba_bios.bin on MyDocs.

Since we can't provide you one due to legal reasons, you can eighter dump one from a gba, or download one through internet.

Once you've grabbed one, make sure to copy it into MyDocs,

then, press the top bar menu of gpSP emulator > GUI Config > Copy bios. Then just select the gba_bios.bin file you copied to MyDocs, the gui will make all the dirty work.

Next step is to select a Directory where you stored your roms,

and the gui will automatically find and list all of them for you. Top bar menu > GUI config > Rom directory.

After that, the GUI may require reboot, so simply close it

and open again, your roms shall be listed for you. Notice they may be on .zip or .GBA or .gba roms.

Select a rom you wish to play, and push "Configure" button.

After this, a list of options will be shown to you, and these options are.:

Options

- Screen options.:

Unscaled : Native gba resolution ( 240 x 160 )

Scaled 2x : Twice gba screen ( 480 x 320 )

Scaled 3x : 3 times a gba original screen ( 720 x 480 )

Fullscreen : Fills up entire N900 screen ( 800 x 480 )

- Frameskipping.:

Off : Do not skip any frames.

Auto : Skip up to N frames ( N avaiable as an option ), automatically

and consecutively.

Manual : Always render 1 out of N + 1 frames, these frames will always

be skipped.

Random Skipping : May make imagine in some games smoother, when

image flickers, but may also make image quality worse, especially in high motion games.

Uniform Skipping : May make image on high motion games better,

just the opposite of random skip.

- Audio Buffering.: Set the size (in bytes) of the audio buffer. Larger values may result in slightly better performance at the cost of latency; the lowest value will give the most responsive audio. This option requires gpSP to be restarted before it will take effect.

- Please, notice that low values are buggy, so please be sure to only

choose values above 4096 bytes.

- FF ( Fastforward ) Is supposed to make emulator run faster than normal, what can prove to be useful in some games ( Subject to test workability ).

Some games workarounds

On some games, you will need workarounds for now to get them working.

-Kingdom Hearts

Simply, before the game freezes on intro video, quicksave the game, then load it back, it should work normally!
