sorry for the very late response
It is almost certainly rendering both PSP and ps1 games at double the resolution of the PSP screen, since the Vita is 2x larger on both axis. There is no way that I'm aware of to force 240p or 272p for ps1 or PSP games. You might be able to do some trickery with an external scaler like a framemeister but I wouldn't count on it.
I checked my vita that does not have henkaku and it look like the PS1 games do play on x2 the original resolution but it looks fine because the vita screen is small (
)
BUT in adrenaline on my pstv I have the choice for psp environment/games to make them play on x1 the original resolution of the psp
while ps1 are still forced to play x2 the resolution and even that looked off
so I checked adrenaline github and found out that 4.1 acknowledges that the pstv have a fucked up resolution for ps1 and it fixes it. So after trying it out the resolution on the pstv is not fucked up but it is still forced x2 (I guess that is because the system uses that as the "original" option)
since adrenaline can force psp games to be x1 I think it can also force it on ps1 games.
I still hated the bilinear filter which I cannot turn off on 4.1 so I updated to adrenaline v5 and that one is all sorts of bugged on the pstv at least
v5 problems that I found:
1) BOTH psp environment and games are forced full screen even if you change their resolution to x1 in the setting
2) ps1 fucked up (fucked up as in its not even correct double the resolution) x2 resolution is back from before the 4.1 update
3) the feature that is most wanted by me which is to turn off bilinear filtering is bugged and force turn itself on regardless of the sitting
4) bonus bug when I pressed the home button to quit the ps1 game (for the psp native menu) it was invisible despite it being functional (yes if you remember the key strokes you can quit the game although you can't see the menu) and it looks like what triggers this bug is turning the filters off.
so my current options are:
1) revert back to 3.1 to turn off the filters but suffer the ps1 fucked up resolution (no x1 and the x2 "original" is not displayed correctly).
2) revert back to 4.1 so the x2 resolution for ps1 games is displayed correctly but then I cannot turn off the filters. and of course I still can't play ps1 games on x1
They talk about Vita and PSP PS1 display options in
this video. Maybe that clears things up
Thank you for the video. It doesn't help my situation but it is informative nonetheless.
New version of Adrenaline is out! Thankfully fixes the slowdown issue with PS1 games by providing an "original" filter option.
I don't advice anyone to update to this yet (at least not on the pstv). It has all the problems from the previous versions and the "filter off" option is bugged and force turn back on regardless of what you have in the settings.
How do you configure plugins in Adrenaline? Like the recently-compatible Categories Lite. What do I have to do make it work?
As far as I know the latest version only works on 6.60 so you need to find a modified version to make it work on 6.61 psp firmware which I have no idea where to find. if you find out please let us know because I'm interested too.
I asked last week, but I guess my question got lost in the midst of news and cool new things. What's the best/easiest way to edit a bubble's title? I used to have to download the db.app, modify it and upload it again. Is there anything better than that, or should I continue with that method?
I think it is still the same but I'm not following this particular issue so maybe there is a new tool that does that for you that I'm not aware of.
