Re: Another "cannot get CF2IDE to work in DOS" topic

Can you connect this CF2IDE (again) with this particular card to your P75 computer and detect card from BIOS ? Unfortunately 8GB limit may apply to P75 as well :( I dont have the P75 around, it would take some logistics so will try that when everything else fails. Its just a generic build I guess, …

Can't it be a 3.3V vs 5V thing? I vaguely remember my adapter coming configured on 3.3V (despite 5V being labeled ad default on the adapter) and having similar issues before realising this. In my case it would see the CF card but any write operation would fail. Frankly I have no idea, but this is …

So you just typed some random numbers for geometry? Not exactly random, I used those people recommended to achieve 512 or 256MB sizes. It was said that the numbers should not matter much as long as the final size is right. After all there is no such thing with the CF. But maybe it meant only …

First, I have read tons of topics on CF2IDE here and it helped a lot, but still cannot get it to work. My 486DX2 has only one IDE channel - used by a 250MB HDD and a CD-ROM (CD-RW to be precise). And I would like to have a CF in there too. After a lot of fiddling around, I managed to get my SB16 ( …

Because I seem to keep starting again with DOS C programming every few years, always facing the same problem and Google repeatedly brings me here to my own question, I am posting the solution , also to have some kind of closure :-D So the reason I cannot allocate a 64kB array is due to the limited …

Ok so as only one person realized there is no MT-32 support in The Cycles, I am writing it here to close this up. I created a fake setup with that option added to make it look authentic. And then I re-created the music from scratch on my MT-32, trying to keep in style with the Adlib version. So at …

Hi folks, I have recorded a short clip of The Cycles with its classic music on my Roland MT-32. Originally I wanted to record it on my old DOS PC, but I dont have the means for that so it was recorded using DOSBox + Munt. Maybe someone else liked the music and while the Adlib is nice for this kind …

Lost in Time CD version - wont run on an old PC

I have found several topics about this game here, but all involve DOSBox. I downloade four "different" versions of the CD version of the game and while they run okay in DOSBox, they all lock up on my Pentium 75 just after executing it. A black screen and pressing keys eventually leads to beeps, so a …

I'm trying this out today and should release a new track in the next few days, a kind of transcription from a piece written in Studio Session (1986) for the Macintosh. I needed quarter note triplets, which wasn't too hard to accomplish by laying out my eights notes in a larger space and increasing …

What an interesting project and I have only just noticed it, thanks for sharing! Will try on my old PC, I usually use the General Midi option with my SCC-1, but it will be interesting to compare with the MT-32 in game that did no longer had support for it.

Transport Tycoon doesn't really do anything special; it's a protected mode game (using a commercial but uncommon extender) and relies on the VGA card having vesa2/LFB support (it has univbe built-in to support older cards). It doesn't update at the max frame rate possible, usually hovering around …
