View Full Version : PCjr (not Tandy) apps or games?

Well I just got a PCjr and am having some fun seeing what does and doesn't run.

It seems Tandy games do not work on it at all - for instance Spectrum Holobyte's Tandy-compatible version of Tetris. All it shows are colored text characters, no graphics at all just a mess. I'd never read for sure whether or not Tandy games are compatible on the PCjr, and I guess they are not.

I know the cartridge games exist but I've yet to find one that is affordable. What about games that can be run from a floppy? Are there are any standout titles, apps or games, that take advantage of the PCjr's enhanced graphics and sound? I have loads of Tandy-compatible games, but I've yet to find one in Tandy mode that works on the PCjr. I've heard a couple Sierra games, namely King's Quest and Thexder, that may work in PCjr's modes.

Just a few for starters ...


Cartridge BASIC - gives you the easiest programming access to the advanced graphics and sound
ColorPaint (cartridge)
MS Flight Simulator 2.11 (diskette)
Demon Attack (cartridge)
Kings Quest (diskette)
Touchdown Football (diskette)

Yeah, I am aware of the cartridge games, but I'm wondering about games which can be found on floppy disk - I've yet to find any cart games for sale, but may fare better with floppies... and can at least download and write them to try them in the meantime until I find originals. I guess I'm also just wondering if there are any "Tandy" games that work on the Pcjr.

Thanks though, I had forgotten about FS2

I remember there was a hardware hack that would enable Tandy 16 color graphics on the PCjr.

I think it involved an additional chip that was piggybacked on the motherboard
and a few additional wires soldered from the chip to other chips. I installed
this on my PCjr way back in the mid 80's and it really helped make it more
compatible. One of the best games that would work in 16 color mode with this hack
was Battle Chess. With the Tandy graphics and the three voice sound, it was a blast.
Mechwarriors was another game that would run in 16 color mode.

EDIT: I just did some searching and that video hack is mentioned on this link although
it doesnt give all the details needed to do this.

mobygames has all the information you are looking for!

Also, you might find this interesting. It's a WIP that I brewed up a couple years ago and haven't finished. It's not 100% working.

I looked at Mobygames first thing, and the problem is that it combines Tandy and PCjr together, which is lame because it seems Tandy games aren't compatible with the jr. At least I haven't found one yet that is.

That WIP of yours does look very interesting though, I was wondering if something like that existed for the carts! I'll have to see what I can do with it

Maybe the Tandy graphics mod will help?

I'm sure it would be just what I need for the PCjr, but I have a Tandy machine or two. I was just looking for stock PCjr-specific stuff and I'm finding out there's really not much!

Apparently this is because the Tandy 1000 was capable of 320x200x16 and the PCjr was not? A lot of games used this mode

So far Brutman's list (and the one on his site) is about the only confirmed set of software

Actually, both machines are capable of displaying video at your stated screen resolution and colour depth, it's just that their individual hardware implementations differ somewhat..

Going completely from memory here - Thexder should work on a jr since that game checks for it's specific bios rom signature. Another game that you could also try on the peanut (pcjr) is Jet..

King's Quest was written specifically to show off the PCjr's new graphics and sound capabilities.

Yes, King's Quest works quite nicely. And so far I have only gotten one game that is listed on the box as Tandy compatible to work, and that is the first Leisure Suit Larry. And it is another Sierra game. Only worked after disabling PCJRMEM from starting with DOS.

It seems there are a scarce amount of games that work on the PCjr that were designed for Tandy. May make a working list of these, as I can't seem to find a source of the games that for sure work on a PCjr. Tried Thexder which was supposed to work but I never got it to start.

Did you ever check out the INSTALL files many games have? The - again - SIERRA SCI games certainly have them.

That is what I've been using, when available. KQ and LSL seem to detect PCjr/Tandy mode, some games, like Arkanoid, fail when I select the Tandy option. It is hit or miss which is what I'm trying to find put

The game Ghostbusters 1 has PCjr support. I agree a list somewhere would be nice to have. Perhaps even on the wiki.
User Trixter (also of mobygames fame) was at one time collecting up PCjr specific games for showing off his machine. I'll pop him an email and see what he's got since he never seems to be here anymore.

Scuba Venture - the only PCjr compatible game I happen to be familiar with, due to it's PC version.. Comes on cartridge, but you can probably find a floppy version somewhere..

There's a PC version of scubaVenture?
The only one I know of is the PCjr specific version. Ie:
http://www.mobygames.com/game/pc-booter/scubaventure
is not the same as
http://www.mobygames.com/game/dos/scubaventure-the-search-for-pirates-treasure

I've only ever known scubaVenture to be PCjr only, and only available on cart.
that said, a floppy version of scubaVenture is available on the first page of this thread, but it's not official. ;)

I spent many hours playing Thexder on my PCjr..... maybe there's a problem with your diskette.
As I recall it was a self bootable diskette
The game has great 16 color graphics and uses the PCjr sound

I recall there were many games that could be patched to run in Tandy mode on the PCjr.
Not sure if these patches are still floating around on the internet anywhere.

I, sir, have a boxed copy of the IBM PC version of ScubaVenture. Would you like to see? :D

As you can see, it's not labeled "The Search for Pirates' Treasure" at all.. I've never played the PCjr version, only this one, but I love this game, lol - very nostalgic.

Nice. you should submit your box cover scans to mobygames so the title can be cleared up a bit.
So you have the same game as mobygames says, but it looked like it said 1991 on your box scan, and moby has it listed as 1993.
Either way, it's not the same game at all. The PCjr version came out in 1983 or 1984 and looks and plays wholly different than the softDisk release.

Raven

It says 1991 on the box, but 1993 on the disk and in other spots on the box. While quite different, is it still the same gameplay concepts and such? Or is the PCjr version a totally different game?

I have the Scuba Venture game from Softdisk, says 1993 on the start screen, but it will not run on my XT. It claims to need
a 286/386/486 system. The game works fine on my 486.

yeah, it's a totally different game.
I would even suspect that since the PCjr title was pretty obscure, that the 199x game was merely a coincidence in title and was not influenced by the one a decade earlier.

I have not played the softdisk one, but have briefly played the PCjr version. IIRC, the PCjr version is a vertical scroller where you just fall and bump into things on the way down to get points, while trying to avoid sharks and hitting the walls of the cavern. (the PCjr one not being that much fun, which is probably why i don't remember too much about the gameplay!) The screenshots of the 199x game make it look like a horizontal scroller/platformer.

Anyone able to get the Softdisk Scuba Venture game running on an IBM PC or XT ? The game supports EGA so I was
hoping to get this running on my XT (with EGA) but it just hangs after selecting B)egin from the opening menu.
