That music is on the second CD, track 12. The CD version is missing nothing, and nothing has been cut-down. Nothing whatsoever. If you think something has been cut, then you just have not looked properly. It only plays the Character Creation music if you have the first CD in the drive. The game only …

I listened to the YouTube recording you linked to, so I could evaluate the claim about shorter Red Book audio versions more thoroughly. It is true that the MIDI versions of some pieces have in-song loops that are not present in the Red Book audio versions. Examining the MIDI files, these in-song …

Realms of Arkania: Star Trail: Redbook audio or Roland SC-55? Redbook audio. The Redbook audio recordings use Roland SC-55, Proteus-1 samples and an unknown drum kit. I don't know what version people use who say that the Redbook audio versions are shorter, because they are not, they are longer. The …

@all, i am very sad 🙁, the adress line decryption looks good for SC55 ROM 's, i am shure, that data line decryption is also good. Loaded the dectypted 3 files stored as one file is now clearly listable - instruments are now recognizeable - and i can hear, that adress-lines are fine. But useing the …

We have already finished decrypting and decompressing the SC-55 wave ROM data, and are now in the process of interpreting the instrument parameters from the control ROM and translating them into corresponding SoundFont generators. At least to the extent that this is possible -- the SoundFont …

The SC-55 wave ROM uses 8.25 bits per sample: 8 bits of mantissa for every sample, plus 4 bits of base 2 exponent (i.e. left-shift count) for every 16 samples. The encountered maximum shift count is ten, making the decompressed wave ROM samples 18 bits wide, even in the original SC-55. Mantissa and …
FixMPU: Software solution for "hanging note bug" on SB16 with DSP >v4.06
Posted on 2020-10-31, 14:41
FixMPU is a software solution for the "hanging note bug" encountered when using the MPU-401 interface of Sound Blaster 16 cards bearing DSP versions greater then 4.05 and smaller than 4.16. Refer to this wiki article ("Type 1" only) for a more detailed description. FixMPU acts as a launcher for the …

kitrinx and I made some substantial progress on the SC-55 wave ROM front. We have successfully understood the process of address scrambling . kitrinx connected a logic analyzer to log the address fetch patterns when playing a single piano note. It looked like this (identation mine): 60455 70B20 …
Re: Creative AWE64 Gold + Roland SC-55mkII Midi Strange Problem?!
Posted on 2020-10-24, 18:30
I see two issues here: The AWE64 Gold's MPU-401 interface, and its DSP, both share there same IRQ level. Games that are not prepared for that situation will behave erratically when both are used together. The solution for that issue is to disable the MPU-401 interface's IRQ using Creative Labs' …

Is there any chance the game executable is looking for something on the disk (weak bits, half tracks, etc.) and running differently if it doesn't find them? No. When I say that the keydisk protection scheme "wraps" the program file, I mean that the keydisk checking routine replaces the protected …
Re: An AdLib-Compatible Card (1986) Older than AdLib (1987)

If so, the "OIT" acronym presumably represents "Office of Information Technology," which makes me wonder if the card may have been a component of some campus-wide video/teletext system or similar. How appropriate that both the original YM3526 and YM3812 are described as being "designed for Captain …

The 5.25" disk's content is identical to the 3.5" disk's, except for the fact that TRILOGY.COM is wrapped with the Formaster Copylock keydisk checking routine. So, no long-lost version with correct gameplay. 🙁

I have asked on TDC for anybody to contribute an image of the 360 KiB version. Let's see what happens. The 360 KiB version is listed as having some kind of key disk copy protection scheme in a list of copy-protected games by Moebius, of The Good Old Days. Since the commonly-available version does …

The only one I can find looks like the label was printed on a dot matrix printer and is text only. Sounds like a "Slash" release. I'm not very familiar with TDC - does it contain photos of the actual copy of the game the disk image was made from? Not that I know of. But the disk was originally …

TDC has a Kryoflux image of a 720 KiB disk of the game. The files are identical to yours, with the exception of additional "AUTOEXEC.BAT" and "GO.BAT" files. Unless somebody unearths a 360 KiB disk of the game with different files (such as this one or this one ), I would say that the finding is just …
