NGPsp is a Neo Geo Pocket emulator for PSP. Based on NeoPop by neopop_uk. ==Installation== Folder structure: * ms0:\PSP\GAME\NGPSP\. * ms0:\PSP\GAME\NGPSP\Battery\. * ms0:\PSP\GAME\NGPSP\State\. * ms0:\PSP\GAME\NGPSP\Roms\. Copy EBOOT.PBP to PSP:\PSP\GAME\NGPSP\. Copy your roms to PSP:\PSP\GAME\NGPSP\Roms\. Supports formats are ngp, ngc, NGP and NGC. It does not support zip format. ==Controls== '''Neo Geo:''' Cross - A button Circle - B button Start - Option button (like start button) Select - return to menu '''Menu:''' Up/Down - Change Selection Left/Right (on number options) - Change Value Circle - Change value or take action ==Screenshots== https://dlhb.gamebrew.org/psphomebrew/ngpsp3.png https://dlhb.gamebrew.org/psphomebrew/ngpsp4.png https://dlhb.gamebrew.org/psphomebrew/ngpsp5.png ==Known issues== Samurai Shodown 2 & Last blade have some serious issues with the emulator. Both games will lock up for a few mins durring a battle then resume but yet keep repeating this every so often. Report of Sonic not working in v1.3 (seems to run well on v1.3.1 at 333 and a frameskip of 4.) ==Changelog== '''v1.3.1''' *This build defaults to 333Mhz as it was a development build. You can still downclock the emu to 222 via the menu. * Removed VSync from rendering. Games get a small boost and framerate is now around 40-50 fps in most games. A improvement over being a pretty solid 30. * Sound code is there but ungodly bad. I left it in this build in the hope someone can help me out with correcting it and getting it accurate. * Suport for using a real bios added but disabled in this build. *Ps. I officialy changed my name from nexis2600 to PSmonkey now. '''v1.3''' * Speed improvements (listed below). ** Some games are now running at 30-35 FPS with a frameskip of 1 (at 333Mhz). ** Puzzle Link 2 now runs at 45-60 FPS with a frameskip of 4 (at 333Mhz). * Allow for a few instruction runs before checking timmers/triggers (vblank & interupts). * Added in a faster FETCH8 by making a special case mem read to check the rom space first. * Added a Load24 and write24 to mem.c to speed up the fetch24 function. * A color bug in B&W games was fixed. * Added a key configuration menu (button config is saved to memstick). '''v1.2.1''' * User Cpu Clocking. You can now change the CPU speed of your psp. * WARNING - By changing the CPU speed you accept full responcibility for any damage your psp might occur. '''v1.2''' * Implimented CZ80 core but seems slower then old Z80. So Code there but not being used. * Analog Stick Suport. * BG added (walpaper.bmp needs to be in same folder as rom). * Small speed boost. * Cleaned up Src (a bit). * Save Ram Working. * Save & Load States Working. * Added exit option to menu. * Learned how to spell his¡Pto¡Pry. '''v1.1''' * Reverted to some old code to fix some bad hacks made from s60 port. * More games working (like metal slug). * Small speed boost. '''v1.0''' * First build. * Basic menu. * High compatibility. * Slow but decent FPS. * No Sound. * Suports NGP (B&W) & NGPC (Color) Roms. ==Credits== Based on NeoPop by neopop_uk.
