NesterJ for PSP is a Famicom/Nintendo Entertainment System emulator for the Sony PSP. Written by Ruka, it is a port of NNNesterJ (a NES Emulator on the Windows platform, modified from nesterj) with features arranged uniquely to the PSP version. It is also compatible with NNNesterJ's SRAM and STATE files. ==Features== * Save states. * Screenshots. * Famicom Disk System emulation. * TV out. * Speed mode toggles. * Show FPS. * Black and White mode. * Alternate palettes. * CPU clock frequency adjustment. * Sound frequency adjustment. * Use of extra sound channels. * Custom key mappings. * Custom backgrounds (in file browser). * Screen size adjustment. * GFX filtering. * Text/cursor color changing for the menu. * Cheats. * Other miscellaneous options. ==Installation== For v1.13beta2 (without adhoc): *Create a folder in the form of /PSP/GAME/NesterJ/ on your Memory Stick. *Open NesterJ_v1_11, copy famicom.dat and MENU.png to the NesterJ folder. *Open NesterJ_v113beta2, copy EBOOT.PBP to the NesterJ folder. For 1.20beta2 (with adhoc): *Create a folder in the form of /PSP/GAME/NesterJ/ on your Memory Stick. *Open NesterJ_v1_11, copy famicom.dat and MENU.png to the NesterJ folder.

Start NesterJ and select the ROM you want to play against. *Select Wifi Network Play(Adhoc) in the menu (make sure to turn on the Wifi switch on the left side of the PSP before selecting). *One party send connection request and the when the other party receive a connection request from another PSP, press the Circle key to accept.

Also, the NesterJ settings for each PSP must be the same. *It may occasionally stop responding during the communication test. *The sound is strange because the sound processing has not been adjusted yet. *Communication processing timing is slow. *It is designed to not use skip frames during NetPlay and the recommend CPU speed is 333MHz. ===How to use cheats=== Create a folder with the name CHEAT in /PSP/GAME/NesterJ/ folder.
