Bugfixes
The original C64 version has a custom charset, as well as an interesting BASIC extension coded in machine language. Neither of these were converted, and the omission of the latter makes the game impossible to complete.

The issue is with line 5000:
5000 F=0:GOSUB 30000+100*RR

That does not work in BASIC by default! RR is the room number. The author wanted to have different code for each room, so it's a GOSUB to 30000, 30100, 30200, etc. Without the BASIC extension, this code would simply evaluate that to be "30000", skipping the +100*RR part. This is exactly what happens in the Plus/4 version, therefore, things that are room specific never get executed.

To fix it, we must use an ON GOSUB statement (only available in BASIC V3.5). Enter the following 4 lines:

5000 f=0:onrrgosub30100,30200,30300,30400,30500,30600,30700,30800,30900,31000
5001 ifrr>10thenonrr-10gosub31100,31200,31300,31400,31500,31600,31700,31800,31900
5002 if f then print"Das geht nicht.":zg=zg-1
5003 ff%=f:return


Similarly:

10010 ontgosub11000,11100,11200,11300,11400,11500,11600,11700,11800,11900
10011 ift>10ont-10gosub12000,12100,12200,12300,12400,12500,12600

Additionally, there's one bug in line 2744, enter this to fix it:

2744 print"los...":return
