Re: SCPH-7502 = Better graphics ? ("PS1.2")
Maybe I can try it and we can worry about saving the bitmap if the results are worth it?

Re: PSX BIOS from PSP 6.60 optimised to play games more smoothly - but in what way?
Thanks for the insights! So why does using PSP 6.60 BIOS run games better than the POPS BIOS?
The difference is very noticeable, I'll make a video soon.

Yes, using game specific cheat codes: http://www.chrismcovell.com/psxdither.html
@nocash @AmiDog what was the conclusion for PSone/PS2?

Re: SCPH-7502 = Better graphics ? ("PS1.2")
For completeness, I've made a texture shading comparison image with screens taken from my DTL-H2000 (which had the old GPU) and SCPH-7000 respectively. I captured the screenshots via framebuffer reads for maximum clarity. Shading is from maximum brightness (255) to black (0). And yup, texture shadi...

Re: PSX BIOS from PSP 6.60 optimised to play games more smoothly - but in what way?
The benefits will not help with games that suffer large issues, such as the slowdown in Sheep Dog 'n' Wolf (love that game). At least using POPS on PS2 it's still choppy when there's a lot of transparencies. But for other games that have occasional slowdown, such as PANEKIT, it improves the experien...

I also read that the Memory Card manager and CD Player have been stripped out.

Re: PSX BIOS from PSP 6.60 optimised to play games more smoothly - but in what way?
Looking at no$cash BIOS analysis, there is much room for improvement in: • memory handling • GPU access • BIOS access caching https://problemkaputt.de/psx-spx.htm#kernelbios So it would be a fair guess that they improved the BIOS in those ways so as to squeeze extra performance out of the P...

Re: PSX BIOS from PSP 6.60 optimised to play games more smoothly - but in what way?
I had dismissed them adding PSP specific functions/hooks, because the BIOS works outside of PSP. Such as in all the emulators I tried. IDA Pro crashes when trying to open as a PSX BIOS, so I guess it's quite different in some way? I can open and disassemble as regular MIPS code though. edit: 17 July...

PSX BIOS from PSP 6.60 optimised to play games more smoothly - but in what way?
Hi all! As you know it's possible to buy and download PS1 games from Sony's PSN service. This selection of PS1 games are playable on up to three platforms: PSP, PSVita and PS3 (which platforms exactly depends on the individual game release). I recently read several mentions on various forums about t...
