un jammer lammy is pretty unplayable as a game but i love lammy lamb and i will protect her at all costs
@Terxbor oh i thought you deleted because of my response
anyway, i think parappa is way more forgiving, at least on that game i can get past the first stage
@squirrel I found Lammy and Parappa playable back on a PS1 + CRT but the re-released versions just don't work because they never solved the lag problem.
I kinda wonder if there are rhythm games with ASIO support?
@rainwarrior bleh
i tried burning it for my ps1, but...
(that's not region lock, that's anti-piracy because it knows i have a modchip) https://computerfairi.es/media/rdRc6FpsgCLu3f52Fgw
@squirrel
Well, I found it at least more playable than Parappa the Rapper, with the timings being significantly more forgiving. (The same could be said about Guitar Hero 2, concerning HOPOs.)
On a side note, I HATE that Mastalab seems to have no option to default my Toots to public+timelines.
