Nemesis

http://www.retroarchive.org/cpm/games/nemesis.zip (manual included)

Using termdef.com we can change terminal type (VT-52 in list and works but terminal test doesn't draws correctly).

At first we need to create character (or use predefined ARAGORN) using person.com program.

Then run nemesis <character name>

After character's death file with character will be deleted.

Can we run these programs?

Can we run these programs?

I do not think so.

Those conversions are to revision 5 and revision 6 of Infocom's Z-CODE, and the interpreter that we have only handles revision 3 or earlier.

BTW, it is fun to see all of Brian Howarth's adventure games being preserved on that site ... he worked at the same company as I did for a while.

But anyway I can't run this game at IS-DOS. It just freezes.

The game's loader program overwrites some of the memory reserved for EXOS, and so crashes the Enterprise as soon as an interrupt occurs.

I have patched ORBQUEST.COM and ORBQUEST.OVL to fix that, and have put the correct terminal settings for IS-DOS into the TERM.CTL file.

The game isn't a lot of fun to play, but at least it works now.

One thing to note, is that you MUST press the SHIFT key on the keyboard to enter upper-case characters when the game wants them. Upper-case and lower-case letters have different functions in the game.

BTW, minor offtop.

Here sources of Z-machine interpreter for retro machines: https://github.com/ByteProject/Puddle-BuildTools
As I understand, it supports z3 and z5 versions.

Hi, I just wanted to drop a note here, that IS-DOS support is now added to ep128emu-core emulator version. And it would not have happened if I did not see this thread but it made me realize that some games do need this OS. It is a niche segment of a niche segment, but I tried a few and it can be entertaining, so thank you for collecting and porting them!

Vezza, a new Z-Machine for CP/M

https://intfiction.org/t/vezza-a-new-z-machine-for-cp-m/57636?page=2

Major features:

Supports z1-z8 (z6 is limited to non-graphics)
Faster than the original Infocom interpreter
Named file save/load
Reverse text
Timed input (1 second resolution)


Tried to load some .z5 games (vezza-sc.com), but interpreter said about insufficient TPA memory.

With another executable (vezza-ma.com) game loaded, but terminal type is incorrect and typed commands have some glitches:
