PicoDrive for PSP v1.50 - Genesis/Sega CD Emulator for the PSP

[notaz]

one thing taht bugs me though -

In Dungeons & Dragons - Warriors of the Eternal Sun, when you walk into the cemetary just outside the castle and look at any of the headstones inscriptions, the game gets stuck and you can't move. Teh music continues to play, but you cannot walk away.

Just fixed it, thanks for the report.

How duz Virtua Racing run on this new version of picodrive ????? Coz it runs superb on the gp2x version

It needs a dynarec (special version for PSP), and that is difficult to make.

I should warn everyone to be aware when extracting this directly to their PSP (or even just copying it manually onto there) - you need to make sure the "Archive" flag isn't enabled for the directory, particularly if you store your roms in the same place as the emulator.

If it's enabled, then PicoDrive will assume that its own folder is an archive and report an Invalid Archive error if you try to look into it (the rom browser starts off outside of the directory and in the area where your other game folders are). I'm not too sure whether the flag is a problem with zipping it up in the first place, but it is very easy to not notice it until you attempt to use it. This problem has existed in all versions of the program to date.

Strange, will try to check what's going on.


I'll probably won't make it with the bugfix release I promised earlier, so it's pushed to the next week.

No, it's only badly coded game. It has an input read routine, which only checks which buttons (of SABC) were just pressed (it ignores buttons held or released). So only first call will 'see' that something was pressed. The routine is called several times per frame, first (if counting from active display start) to check for d-pad buttons, then SABC, so that first call 'eats' SABC, while the game doesn't check for them at that time, it uses later calls for that.

this is indeed a timing issue: updating inputs at the start of vblank (instead start of frame) solved it

thanks a lot

[carpy]

[notaz]
