PSP is still one of the best devices to play PS1 games on a handheld. Thanks to the built-in POPS emulator, you can create your own EBOOT.PBP filesand play them with your PSP.Every PSP firmware has a built-in POPS emulator and compatibility of PS1 games change with every version of POPS. Generally later versions have morecustomization options and deliver a better experience overall.PS1 games generally have 2 kinds of streaming audio, XA and CDDA. CDDA is uncompressed redbook audio while XA is 1/4 lossy compressed. So CDDA audiodelivers a much better audio quality in the games it was used. Unfortunately any POPS version bundled above 4.01 PSP firmware has actively disabledCDDA audio for homemade PS1 EBOOT.PBP files. You hear silence instead of CDDA audio if you boot these games. That is not valid for PSN releasedPS1 games as Sony uses a property compression algorithm for CDDA audio on these games.To overcome this limitation, you can use POPSLOADER plugin to load a POPS version equal or prior to 4.01. This will cost you 2 things. 1)Less customizationoptions of POPS 2) Bad compatility with PSP3000 and PSPgo series. Especially if you have a PSPgo, every POPS version supporting CDDA audio withPOPSLOADER will either blackscreen or output audio only from headphones.Now with CDDA Enabler, you can enable CDDA audio on PSP firmwares > 4.01 without enabling POPSLOADER or having compatibility problems with your homemadeEBOOTs. It just works.
– Copy ‘cdda_enabler.prx’ to the ‘seplugins’ directory of your Memory Stick or Internal Storage of PSPgo.– Add “ms0:/seplugins/cdda_enabler.prx 1″ (or “ef0:/seplugins/cdda_enabler.prx 1″ if you are using internal storage of PSPgo) line to the end of ‘pops.txt’ in ‘seplugins’ folder.
– Rip your game via using .ccd .img .sub format, unfortunately that is the only format supported for cdda. .bin, .cue will not work. Alcohol 120% and other rippers support this CloneCD format.– To test the cd image before converting, mount it with daemon tools or some loader like that and be sure your pc detects extra audio tracks and play them just as it would play an audio cd.– Use the latest PSX2PSP (1.4.2). Some other converters do this too, but they need a modified exe or some other stuff etc. Use 1 or low compression like 2-3. Do not use 0 compression.– Transfer the resulting file to your PSP and load it from XMB with CDDA Enabler plugin enabled.– Enjoy your CDDA audio.
