Hi at alls, i am a big fan italian of AMSTRAD CPC scene, i have tried at dumping many my old tapes, but I found several problems with some games that use special protections.
The programs used by me are: SAMP2CDT, CPCTAPEXP, Audacity.
I saw several protections Speedlock but many are not supported by samp2cdt,.
The problems I had are with the following titles.
Let's face it straight right there. I'm going to tell you about every protection scheme i have deal with CNGSOFT
SORCERY (flashloading version)
=>
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=1988Gauntlet 2 (border green and cyan) dont 'work in the emulators, impossible.
=> Gauntlet 2 is using the USGOLD loader (samp2cdt /usgold gauntlet2.wav gauntlet2.cdt) for the main part,
and you must use the Speedlock Data Type 1 (samp2cdt /sldata gauntlet2.wav gauntlet2-dat.cdt for the levels.
Note that this game needs cleaning the noise (i have found the perfect settings to dump any tapes even the wierdiest).
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=961MOT
=> Use the opera soft K7 protection. Unsupported by all the softs.
Just one question, do you own the english version of this game ? If yes, please contact me on MSN dlfrsilver AT hotmail DOT fr.
CNGSOFT has converted his own tape of MOT (spanish release).
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=1462DOUBLE DRAGON DOUBLE DRAGON & 2
=> Double Dragon uses a speedlock v4 for the main part and a spectrum variant 3 loader for the levels
samp2cdt /slock4 ddragon.wav ddragon-code.cdt and samp2cdt /specvar3 ddragon.wav ddragon-dat.cdt then glue both parts to get a complete CDT of the game with CPCtapeXP.
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=1150=> Double Dragon 2 uses a speedlock v6 for the main part and a spectrum loader for the levels
samp2cdt /slock4 ddragon2.wav ddragon2-code.cdt and samp2cdt /spec then glue them with CPCtapeXP.
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=404CONTINENTAL CIRCUS
=> This one uses a speedlock v6 for main part and spectrum loader for data levels.
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=607PUFFYS SAGA
=> Use an unsupported copy protection, it's a variant of the UNILode (UNIiversal Loader Oxford Digital Enterprises, the company behind the trivial pursuit computer games). You won't be able to process it yourself.
I have dumped the game, and it's available in splitted version on the best CPC website on the web, called CPC-power. Go check it and pick it up
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=1716GET DEXTER 2
We lack this game, there is 98% of luck that this one uses a micro-key copy protection.
Please contact me on MSN in order for me to help you to dump it

LEMMINGS
This game use a Speedlock v7 for the main part, and a speedlock Data type 3 for the levels data.
You must know one thing, the coders have not removed the demo code limitation, this game must be poked to be able to choose the
level you want to start at.
http://www.cpc-power.com/index.php?page=detail&onglet=dsk&num=1293Please advice?
I see which many games converted in to .CDT, with protections not supportet by SAMP2CDT. 
Easy, all the games like trivial pursuit, opera soft, puffy's saga, red arrows, dick tracy, Franck Bruno's boxing retail version, Knight Force,
After the war, astro marine corps, jabato, Captain trueno, and a few others can't be done with the actual tools.
To dump the tapes, use Goldwave. This one is way more accurate when doing CPC tape dumps.
You can believe me, as i have dumped more than 500 games on my own head to this day (speedlocks, alkatraz, cassys, bleepload, etc).
