Potential Workaround for PS1games incompatible w/ Adrenalin
Posted: Sun Nov 26, 2017 5:09 am
As many will already know Adrenaline is not compatible with those PS1 games that do not run on the default version of pops and theFlow has made it clear that the PSP CFW popsloader utility cannot/will not be ported to Adrenaline. That's not a huge problem if the game works on the Vita version of PCSX Rearmed Retroarch instead, but if that doesn't work well for the particular game in question, or, you just doesn't like using retroarch, then here's a (possible) work-around I stumbled upon where uncompressed PS1 custom eboots work on PSP but do not work on Adrenaline.
There may well be many already familiar with this work-around but I am posting this because it took quite a bit of Googling before I stumbled across it and I suspect that many users will, like me, try an uncompressed PS1 game with Adrenaline and just give up if it fails to launch a few times or else spend hours trawling the net to see if they're doing something wrong just because some other forum user insists said game works fine on their end but can't say why (as was the case with me).
The work-around is *compression*. If the ISO/bin-cue to Eboot conversion (via psx2psp or icetea or what have you) utilises additional compression, then the game should load. . . - or hopefully at least, as that was the case for me with all 4 of my games which ran fine uncompressed on PSP hardware via non-default POPs vesion configuration with Popsloader but would not work on Adrenaline for obvious reasons (no popsloader). Converting the iso or bin/cue into a new eboot with the compression slider set to just level '1' allowed these games to run in Adrenaline. I *think* I also tried converting a CSO into an otherwise uncompressed eboot (so leaving compression level at 0 during the conversion process) and that eboot worked too but I could be misremembering that one as it was weeks ago and I'd just come back from the pub!
The games that I managed to finally get working in Adrenaline via this method have had no issues thus far but
for the unfamiliar, it's worth bearing in mind that there are possible downsides to compression depending on the game and sometimes the degree of compression but these are well documented and easily googled.
TL/DR: If you are desperate to get an uncompressed PSX eboot to work in Adrenaline but can't get it to load properly, try recreating the eboot in question and using some level of compression, or, just try converting an already compressed CSO into eboot.
