I picked up an original copy of Goonies on 5.25 disk. I'm trying to get it working on my C128D but after LOAD "*",8,1 it makes a little drive noise and then goes to a blank blue screen. It just hangs there. I did start up the C128D in C64 mode. I tried with & without jiffydos enabled.

Is there a way to play the Goonies on a C128D? Or does it use some copy protection scheme that only works for a 1541 & C64 set-up?

Thanks.

I believe The Goonies was one of the games which didn't work on C128s without a workaround, which from memory was using caps/shift lock while it loaded in this case. Wanted Monty Mole is another one.

It's due to that bug on the C128 which causes one of the characters not to be capitalised or whatever - I forget the details as it's never been a problem for me, but I'm sure someone here will care to clarify what I'm saying Smile

I tried loading the Goonies on my C128D with & without the shift-lock pressed. I also tried just holding the SHIFT keys too. But no joy. I press the key right after typing load"*',8,1 & hitting enter. Should I press the key at a different point? Am I pressing the correct key to address the bug situation?

I took a look at my Maverick Parameter disks and one volume has a parameter for the Goonies. It's a custom copier and says 1541 only. I tried using it with my 1571 and it wouldn't work.

I do have an external 1541-II (no jiffydos) set as device 9. I can't load the Goonies from there because it will look for device 8. Can I softwire the device numbers for loading games?

Any other suggestions?

Bruce Lee is by the same company as The Goonies (DataSoft). I have an original copy and it works on the 128D.

Caps lock.. on the top row. Not shift lock.

Found & tried the capslock too but nada. Goonies will start loading, the screen goes blue, drive light stays on, and that's it.

I'll see if I can get hold of a C64 to test the disk on.

I've been reading some pages about the capslock & Q bug. It seems that this bug was fixed in later versions of the C128D. My C128D is the model with the metal case, not the plastic one, and it has 64k video RAM.

So I'm wondering if it's a 1571 issue, a C128D issue, or a Goonies disk issue. If I can, I'll try the disk on a C64 system this weekend.

According to some info about the differences between the 1541/1571 drives, the Goonies might not be 1571 compatible even when the 1571 is in 1541 mode. Has anyone successfully loaded an original version of the Goonies using a 1571 drive?

That protection does use "weak bits" or simply intentionally bad GCR sequences.

When a track/sector contains more than '3' off-bits in a row, or really, just absence of any flux change for a certain time, the CBM hardware gets "lost" or out of framing. On a 1541, you get a semi-known pattern where it injects false 1-bits into the byte stream, but some 1571's will return real 0x00 bytes, and others will return "random" data that can even contain syncs. It's possible what your 128D drive returns fails this protection check.

Usually the protection reads the same area on the disk one or more times and verifies that the byte stream is different.

I've found the key to One Eyed Willy!

Ok. I used this command to disable the internal 1571 on my C128D:
OPEN 1,old,15,"M-W"+CHR$(119)+CHR$(0)+CHR$(2)+CHR$(0)+CHR$(0):CLOSE 1

I found that command line here:
http://commodore128.mirkosoft.sk/herdware.html

I connected a 1541-II drive and set its jumpers as device 8. I also pushed the caps-lock (I'll have to try without the caps-lock next).

Insert the Goonies disk in the 1541-II and LOAD "*",8,1
A lot more drive noise this time and success!. Apparently Goonies does not like my 1571.

There are two version of The Goonies- one (that is suspected to be the PAL release) has different music instead of the "Goonies are Good Enuff" Cyndi Lauper song...

Any idea why? Licensing?

HSVC labels the other one as the tape version, and my tape version indeed does not have The Goonies "R" Good Enough on it.

I have an original disk version with the different music also, so its not just a tape thing...
