View Full Version : Defender arcade on PSP?

December 8th, 2010, 20:30

I have custom firmware 5.50 D3 on my fat PSP with various emulators. I would like to play the arcade version of Defender (8bit I think) and wondered what emulator I need?

Hello gonzouk,

You need MAME4All v4.9r2
here: http://ttyman.free.fr/mameforall/PSP_MAME4ALL_v4.9r2_Hires_by_TTYman_-_16112007.zip

Install directions:

- Copy in /PSP/GAME (firmware 1.5) or /PSP/GAME150 (firmware 1.5 compatibility for 3.xx OE release);
There are four different builds in archive:
1) 1.50 Kernel mode (psp_mame4all_v4.9r2);
2) 1.50 Kernel mode without neogeo and cps1 support (psp_mame4all_v4.9r2-noneogeo-nocps1);
3) 2.00 User mode (psp_mame4all_v4.9r2-usermode);
4) 2.00 User mode without neogeo and cps1 support (psp_mame4all_v4.9r2-usermode-noneogeo-nocps1);
Use psp_mame4all_v4.9r2 as installation base, then replace EBOOT.PBP with your needed/preferred build
- Recreate zipped roms with included ClrMame compatible .DAT files (v0.34-v0.36 mixed roms);
- Add created zipped roms files in ROMs subfolder and samples in samples subfolder;
Samples must be in .sam old Mame pre-v0.35 format, downloadable from http://www.mameworld.net/samples/sam.htm

Thanks for this.

I have it all running, but the 2 games I'm trying "Defender" and "stargate" get stuck on booting up when they load the rom. If I try the roms on my PC's mame they work.

The rom checks go ok and they say something like "reset to factory defaults", the message seems to be part of the rom load not the emulator it'self.

Just wondered if I'm missing something on the setup or you could try loading one yourself?

Thanks in advance
