A Boulder Dash fan wrote me that he had a problem with Super Boulder Dash. This is what he wrote:

I'd have to guess that the game is in NTSC, since it shipped from the USA, but I don't know If that could make it stop loading right away... Confused

Just a thought... EA had a pretty complex copy protection scheme / fast loading utility (it's what's going on when the EA logo is flashing) and I had a few EA games stop during the load utility when the disk became corrupted.

That's all I can think of at the moment. Super Boulder Dash from EA and the box seen above are what introduced me to Boulder Dash. Both sides worked for me in the USA on my Commodore 128 (in 64 mode).

When I loaded it up and started playing the first cave, I fell in love instantly. I had always gone straight to the Dig Dug machines in the arcade and this game blew that out of the water.

The game itself is the unaltered NTSC version on any release, including those sold in PAL countries, thus the non working intermission in BD1.

The problem could well be a custom loader or a copyprotection depending on an NTSC C64.

I don't know if the disk is encrypted (which is the case with more advanced copy protection schemes.) If not, you should be able to just load the game instead of the loader and start it with a sys command.

BD1: sys36432
BD2: sys49152

Ruben sent me a .d64 file of side 1 of his disk.

I managed to load BD1 succesfully when WinVICE is in the NTSC mode. But in the PAL mode the program crashes just after the EA logo has started flashing. So I guess this disk was made for NTSC machines only...

Anyway, the help was much apreciated! Very Happy

As I can remember EA had a copy protection on the disc. Something of a bad sector or somthing like that? Can't remember exactely. I remember exactely that I found a site on the net with information about this disk. It's a site about backuping old C64 games - but you can not download anything there. I try to find it again!

If possible can you ask Ruben to dump both sides again and keep an eye of any method to also dump the copy protection? A complete backup of both sides would be very much appreciated here... Smile

All about C64 copy protections can be found here: http://c64preservation.com/
Super Boulder Dash is also in the data base.

The Microfun and First Star releases are very primitive, as they are merely checking for a missing sector.

I never saw an original copy of Super Boulder Dash, as it apparently is NTSC only, they wouldn't sell it in Europe anyways. The database has listed pirateslayer there which requires a parallel nibbler to copy.

Yes, this was the site! Smile

I think it must be a bad dump. Maybe you can describe exactely how to dump the disk? Or is there any documentation?

It would simply be great to have a working backup of the original Super Boulder Dash collection!
