Getting JJ1 to run: ~Link
As a lot of you have noticed, when you bought your new computer, Jazz Jackrabbit 1 stopped working and you got a horrible error message like:
Runtime error 200 at 0009:37F2
This really disappointed me and probably a lot of you too. And if you did a little more research (maybe trying it on your old computer again), you realized that the problem was because your computer was too fast for it.
Most people probably just eventually forgot about it. But you may have been one of the few who did some more research, and found out about a program called MoSlo.
MoSlo is a program which is supposed to slow down your computer to a given speed in a percentage amount. So for example, you would type: MOSLO
/42 jazz.exe. When I tried MoSlo, it turned out that Jazz 1 ran WAY
too slow at 42%, but I got the error message at 43%. I couldn’t play like that! So I search some more.
I came across a program called TPPATCH
(Turbo Pascal Patch). Any program programmed in TP will have that error message when run on a fast computer (not just JJ1). So I tried the patch on my JJ1, and it worked perfectly! No bugs or anything.
So if you have Jazz Jackrabbit 1, but you can’t play it anymore, TPPATCH
is the program for you:
(the file is in .zip format, and it includes a help file)
The syntax for running the program is (from your JJ1 folder):
Or for Holiday Hare or Jazz shareware:
Good luck with this!
If TPPatch doesn’t work: ~Newspaz
For some PCs, which always happen to be the ones I buy, TPP
atch doesn’t seem to be able to fix the Jazz excutable. I am going to show you how to run Jazz1, on the right speed without TPP
-) Download CPUK
-) Tune your CPU
down to about 166mhz using CPUK
-) Start Jazz1
-) Press Control-Alt-Del, while you see the intro movie
-) The windows task manager will pop up, end CPU
-) Select Jazz1 on your task bar
Note: If you will not end CPUK
iller your Jazz will run like a turtle.
Have some fun :). It worked for me.
Fixing your sound: ~NinjA
This is a guide for using an emulator to make JJ1 sound work.
This guide will make your OMF
work, as well.
First of all, download VDMS
ound from http://ntvdm.cjb.net/
Then, install it, of course. Go to your Jazz1 setup program and right click it and press “Run with VDMSound” Choose the highest quality Sound Blaster settings there are and save changes.
Right-click your Jazz1.exe and run it with VDMS Sound. It should work fine like the good old days.
This also works for many games that don’t work under your new soundcard. :)
