i have a first party 8mb sony memory card that works flawlessly for all my other games (real ps2 hardware, btw) but sonic heroes always just displays the "continue without saving" message between levels, so i can never save my progress. i couldn't find any help for this online
The framerate's definitely way worse but on my CRT it hasn't been the most noticeable and hasn't bothered me. I'm playing it on here because I have a PS2 in my bedroom so I can have a console to watch DVDs/play CDs on in there, and the TV only has one input.
Sonic Heroes does save on PS2, that was my original version. I dunno what’s up with your memory card.
so, weirdest thing ever: the game autosaved on my other (also first party 8mb) memory card just fine. it only doesn't save on my main one, even though it's never had issues with other games and it has more than enough free space (700kb+) for a 106kb sonic heroes save.. at least the problem seems solved yeah, it created a 0% progress save on there that shows up both in the in-game load save menu and the ps2 system browser. it just never saves any progress on that card
Moronic question (as I feel you probably tried this first), but does wiping the save from the PS2 System Browser and letting Heroes create a new save file on the same card do anything? It might be worth giving a shot, as it might be possible it somehow created a semi-corrupted save that it can't properly write to. I've never experienced a PS2 game ever doing that, but who knows. The only other thing I can think of is perhaps moving all of the saves from the problematic card onto a different card, formatting the problematic card completely, and then move everything back and re-try. Though I assume you probably don't have a third card lying around. The PS2 port of Heroes is a fun one! Last I tried to play it my disc was scratched up enough that I couldn't even load Seaside Hill (the game hung on the mission briefing loading screen). I should record that at some point.
While I've never experienced this with Heroes (and I fairly infamously had the PS2 version back in the day), I HAVE seen this behaviour on another PS2 game - my copy of Wipeout Pulse did this and I never got around to fixing it.
I remember my friend's copy of Heroes on PS2 being finicky as shit. We had the same exact issue when he brought over his console and copy when it first came out. Got through most of Team Sonic then woke up to a blank file select the morning after. You'd have to power wash it like an NES cart to get the laser to read it too. As opposed to my Xbox disc which always just werked without issues even scratched up. IDK the PS2 is weird and I was never particularly upset I didn't have one.
deleting the save file and creating a new one actually seems to have worked. the game saves on that memory card now. guess it was corrupted somehow
