Quote from: revaldinho on 23:26, 12 May 23Right, I've just tried this new version using the ROM from the zipfile.On my 6128 + M4, all is well and I can see the updated ROM version in the sign-on message. HDCPM boots into CP/M+ normally. All good.On the 464 + M4, I still don't get to the CP/M+ prompt.Here's the 464 sign-on screen (with 6128 Firmware/BASIC installed and no ROMs other than the HDCPM and M4 support)You cannot view this attachment. Running |HDCPM directly still fails the environment checkYou cannot view this attachment. So, rebooting and running the Dk'Tronics BANK.BAS utility to install RSXes and using the |Emulate command, |HDCPM gets past the environment check but ends up with a solid blue screen and the machine locked up as before.You cannot view this attachment. You cannot view this attachment.

Quote from: GUNHED on 15:00, 14 May 23Regarding CP/M Plus. Please use v 1.1 to have proper SIO support.
Quote from: zhulien on 20:59, 11 May 23@d_kef Does the CPM Plus that I posted in the other thread work for you? It has been patched and used to work on my 664.https://www.cpcwiki.eu/forum/applications/dragonbreed-patched-cpm-plus/

I suppose the DISC.BIN contains the CP/M Plus BDOS, BIOS and CCP but it isn't compatible with HDCPM.d_kef

I suppose the DISC.BIN contains the CP/M Plus BDOS, BIOS and CCP but it isn't compatible with HDCPM.d_kef@zhulien I did some further testing and the DISC.BIN is indeed a normal .EMS file with an AMSDOS header so it can be run from Basic.After removing the header I was able to make my CP/M disk image bootable with it.It loads just fine but not on my 464! It still uses #C3 RAM mode (confirmed with WinAPE) and unless you had a Dk'tronics or revaldinho's RAM card attached I don't see how it could have worked with your 664; Or I miss something here...I'm attaching the extracted .EMS file here for anyone who wants to test it.d_kef
Quote from: zhulien on 03:40, 16 May 23I've always wondered is a 6128 version of a 256k memory expansion really 256k or is it 192k?
Quote from: d_kef on 19:02, 15 May 23Thanks for the files @GUNHED !!!Do you know if the first one is an official AMSTRAD release?I assume the second one is v1.1 patched for Vortex formatted disks?d_kef
Quote from: zhulien on 10:11, 08 June 23On my 464 without dd1 but with m4, 6128 roms it locks up. Sorry i dont have a working dd1 interface currently but if my memory is working, my friend used to use cpm plus on his 464 without issues... with 6128 rom and dd1.On my 664 if I don't have a disc in drive a when I boot it locks up also, but with a disc it works fine.I am wondering if it is trying to login the disc. Maybe I will try on winape, but I am sure you have already?I will do some more tests with different memory expansions to see if the behaviour changes. I have dktronics, xmem and now Gemini.
Quote from: d_kef on 21:10, 08 June 23I can't even try the USIFAC's FDC emulation because my 464 aparently doesn't like the USIFAC.
QuoteThe protection was designed by Frédéric SOL, an engineer from Esat Software, known for his Machiavellian protections.He is also the illustrious author of the Amiga and Atari ST copier called Discoscopie (I have it in original), and he too is badly protected against copying, that's the mark of the character.Anyway....Not only does the loader use at least 3 protections, with the following messages: "1987 F.Sol - All rights reserved"- 1st post: "Please wait. "The program is loading"* 1st anticopy test: "Please unplug your Multiface"* 2nd anticopy test if basic v1.1 is detected: "This cassette version will not work on a CPC 664 or 6128. Use the floppy version."* 3rd anticopy test: "Please turn off your floppy disk drive." Appears if the FDC hardware test is positive... No 464 + floppy drive hehehe!When everything is good and the loader has been loaded, the message "Code Loaded" appears.* 4th anticopy test: Then, a key coded on 1 byte and with a value of &80 is read just before the big block of 64 kB, which does not use any CRC, does not tolerate any error, any cut during the loading.* 5th anticopy test: Data processing is monitored, if it is cut, the game detects it, and freezes or resets as desired.
