PS1/2 PS2 modchip - wired incorrectly? (photos)

[Codename PUMA]

Long story short I made a thread last year that a chipped PS2 I bought doesn't play PS1 games (not even legit ones, unless I turn the modchip off), despite pretty much all attempts at activating PS1 mode (double resets, stuff like that). I got a chipped PS1 to compensate but that's being a bit of a jerk lately and I require a SCART cable with it which means I can only play it on one TV which sucks. So I finally got the courage to rip open the PS2 completely and take photos so I can hopefully get it to play PS1 games once and for all.

The modchip is a Mars II, and it has "M320-L8" on it. I can't find exact photos of the exact same one, nor am I knowledgeable at all that this should look like other Mars photos. I guess I'm wondering if anyone immediately notices something off:

I'll take more if need be, I don't really have access to a that good a camera though.

FWIW it plays NTSC, and back up PS2 games perfectly, and I don't need a SCART cable for it to show up in colour.

Aaaaaaaaaand broke the damn thing. Can't get the controller port ribbon back in on re-assembly. Brilliant.

is this of any help? http://ngemu.com/threads/ps1-games-not-working-on-modded-ps2.78890/

but an alternative i guess you could nowadays get rid of the modchip and install mcboot on the memory card?

edit: also according to this website http://www.game-chip.com/kbank.htm
you must press reset twice for ps1 games

I've tried every kind of reset twice/etc method there could possibly be, really. Thanks, though.

Not that it matters anymore. The memory card/controller port is screwed after I had to flat out tape it to the board. The analog light turns on on controllers but it doesn't recognise button presses or memory cards at all. Gonna have a get a new one, looks like.

Hey, I think I bought this PS2 [emoji28] Photobucket links are broken but this system had the exact same chip in it and the controller/MC module wasn't working when I first got it. Happy to say its working now and I have all your old saves including GTA:SA from 2015, right around the time you posted this. I have FMCB running on it now so if you want those old saves let me know!
