PC-98 (PC-9821 / PC98)

Attached is the floppy image of the PC-98 version.
(Mentioned by David here.)

I created this thread to point to:
http://www.geocities.jp/zarazala_9/kone ... ersia.html
The pages are in Japanese, but they include very detailed information, including information about the location of files, compression, levels, palettes, fonts, images, music, save files, etc.

I guess it would be time to publish my results in this topic from 2010...

It does not seem to work, I just get a black screen.
A few bytes are different between this PRI1.DAT from the FM Towns and the actual PC-98 disk image.
Perhaps because the FM Towns version had CD music, unlike the PC-98 version.
And this might be what causes it to hang at startup.

The PC-98 version used to be on http://princeofpersia.ppa.pl/ but that site now says "Internal Server Error".
You can find the ZIP in the Web Archive: http://web.archive.org/web/201603151104 ... prince.zip
Or from PoPUW: http://popuw.com/files/pc98prince.zip

Note that in this ZIP, the DISK_A.FDI disk image has a part zeroed out.
This causes the game to hang in the intro, after Jaffar saw the prince in the crystal ball.
So this part should be copied over from PRI1.DAT using a hex editor.
I attached this fixed DISK_A.FDI to this post.

the download from popuw works fine unmodified.

you need to insert disk b in the second drive.

with both disks inserted, it plays.

there are two known faults in the conversion i'm aware of.
1) player turns around a little too soon. this changes the timing for 2 tile jump so that you start it from where you end up after climb instead of from edge of platform. i believe turnaround is one frame early. It should be possible to patch this, i think.
2) jump up from loose tile trick seems impossible. this makes the extra life extender potion in level 3 impossible to collect an escape with. this IS intended. that potion is a trap. this extra potion is present in pc98, fm towns, and tg-16 versions. it is not present in x68000 or sega cd version. I'm not sure how to fix this.

to the best of my knowledge everything else works as expected.

so this version is NOT mod perfect.
