Wanderer and SuperGoldCard

It seems impossible to run Wanderer (full version, original) with SuperGoldCard. Is this normal or should I change some settings?
Thanks

You could try RES_!28

Unfortunately Wanderer has to be loaded at a fixed memory address. With expanded memory it can be hit and miss as to whether that address is available.

The boot file should look like:

Code: Select all

10 PAPER 0:WINDOW 512,256,0,0:MODE 8
20 a=RESPR(RESPR(0)-196608)
30 LBYTES flp1_WANDERER_PIC,131072
32 pause 200
35 LBYTES flp1_WANDERER,196608
40 FOR N=1 TO 2500:NEXT N
160 CLS:CALL 196608


RESPR probably will never grab enough memory - what i have done in the past is to add a small loop such as

Code: Select all

20 a=ALCHP(1024): IF a> 196608: GOTO 20


If that gives an error, try RESPR, but ALCHP tends to work better on expanded memory!

Thanks Rich for your suggestion, but unfortunately it doesn't work.
With JM ROM + SGC the QL freezes. With Minerva I got some "out of memory" error.
Anyway, thank you very much for your attempt.

If the QL freezes - that suggests the program is writing to a ROM location. I seem to recall (without looking) that there is a command on the SGC to protect the ROM (as the QL ROM is actually copied into RAM on the Gold Card / Super Gold Card)
