As far as I know, atleast some if not all PSX-Chips should work in a PS2, too.
All they're doing is sending the SCEX-Signal thought.
Yepp, such a 30-50ct-PIC with some code on it as a PS1-modchip + FMCB and some Homebrew is the cheapest and also the best solution thought.
1. You can start PS1-Imports&Backups directly.
2. Nothing in RAM is patched thought, so it stays fully Homebrew-Compatible (all modchips interferre with Homebrew in some way).
3. I guess the old swap-method like with Action-Replay-Max and the old Neo-Chip is possible this way also, so you could even load PS2-Nonpatched-Backups/Direct 1:1-Copies with it (after you pre-booted with a Retail-Disc, but atleast this method will let you use the EJECT-Button there-after... I think uLE would come in extra-handy here.).
So my conclusion is,...
If I really would need to use the laser, while playing all sorts of backups&imports with various ways and while keeping the highest compatibility for Homebrews, I definetly would go for a cheap PIC and flash it myself.
It's not that hard to solder the SCEX to the drive, then for example doing it perfectly for the BIOS-PINs.
Maybe others post their opinions, too?!
Btw.: Maybe HDPRO would be something for you.
The CDVD-Patch-Points should still work (as stated by someone related to the HD-PRO-Team).
