Description from

"A platform shooter from Japan, Thexder offers many levels and diverse enemies that gradually increase in difficulty. You pilot a Battletech-style robot capable of switching from a 'mech into a jet at any time. Your weapon auto-aims, but uses up a fixed amount of rechargable energy; if you run out of this energy, you'll have to wait a few seconds before you can fire again. Your 'mech also contains a shield that can be activated to protect you from harm, but this lasts for a few seconds and uses up some of your life energy."

Architecture: 68k

Requires 2 or 4 color mode.

Playable on Mac OS 7 up to 7.5.5 (tested on 7.1 and 7.5.3) with 32-bit addressing turned off in the Memory control panel.

Just added ThexEdit, a little cheating utility that give you that extra energy boost. I haven't had the chance to test it myself, so I'd love to hear back from others if it is any good? Smile

Most unique arcade game that ever came out on a Mac. In my top ten favorite games list. I had the install disks up until two years ago when I sold it on eBay for $30.00. I never thought I'd be back on my G5 using it as a main computer over my Windows 8 or 10 computers. Might still have it installed on my PowerPC 9600, I'll have to take a peek.
If I am not mistaken a second version was released after this one.

Must be compatible to Basilisk as well.

Yeah I tried to turn it off in BII as well, but the option wasn't there (and the Mode32 cp in 7.0.1 wouldn't run either). I guess it's a limitation with the emulator.

I was able to play the game in 7.5.3 on my LC III with 32-bit addressing disabled. From 7.6 onwards 32-bit was mandatory.

When I turned off 32-bit addressing in the Memory control panel, the game displayed fine.

Thank you for this hint. Unfortunately, my Basilisk (Mac OS 7.5.5) setup didn't accept switching 32-bit adressing off. Even if I set the CPU to 68020 and Mac model to IIci (all of them as the oldest possible setting), the 32-bit addressing forced being switched on.

Probably, Mac OS 7.5 is too new for this game (7.5 broke some apps and games), but 7.1 should those games run fine.

Someone with System 6 and/or 7.1 installed in Bas should also check this game, please.

I remember another episode where a guy brought in a Virtual Boy. Ended up with the Old Man playing Mario Tennis or whatever it was called.

I added a couple of pics of the game in colour, taken on my LC III. The title screen displayed fine but the game was all garbled. When I turned off 32-bit addressing in the Memory control panel, the game displayed fine.

This game is also available for the Apple IIGS.

This is now a Disk Copy 4.2 image, stuffed with Stuffit 4.0, but not taken of off original disk.
If I try to start this is 4 colours in Basilisk with Mac OS 7.5 installed, I get graphical glitches.

To quit the game, simply press 'q' on the keyboard.

Ah, I could only see the top of it, and it looked like a Mac color monitor and some external floppy drives. Some would say the IIGS really was a Mac anyway... Smile

Apple IIGS on Pawn Stars

I just caught the end of an episode of Pawn Stars on the History Channel, and Rick kicks Chumlee and Big Hoss off of an old Mac and starts playing Thexder on it! I don't know if there was anything about it earlier in the episode.
