Yup, that's me! And I'm pretty sure I've seen this video before!

(Great job on 8088MPH, and I've gotta read your blog, looks like very interesting read!)

A thousand times yes!

That's AdLib. I actually know Zedek (who uploaded the video) and he is a FM soundchip enthusiast, so that makes sense.

Also if the game supports standard MIDI output, it might be possible to capture it with some MIDI + DOSBox magic!

You could always try doing it the async way: don't have a tightly timed loop, instead whenever you call some subroutine that would handle IMF playback, just look at how much time has passed and process all IMF events up to that time. I have no idea how well that would work, but it might be way bette...

To clarify, the PEEK(&H46D) and PEEK(&H46C) commands are crucial to how this all works, as they read the timer value that changes automatically (out of QBasic's scope).

(The actual reason is because these are incremented by the PC's timer hardware / BIOS interrupt, just to be exact.)

No problem! I was wondering what that sub was. Didn't affect performance though, as far as I can tell. Well the program changes the frequency of one of PC's timers, which happens to be the one that is also used for date/time, so I backup / restore the proper time after I'm done playing I'm having t...

Well darn. There's something I could have used a few years ago. That's some nice coding right there. Hey, thanks! :] Well the C version is infinitely better, the way I deal with timing here is kinda funny. And there should be a delay between OPL2 writes, as the datasheet says. (also btw, when delet...

And then you're also the guy whom I left a YouTube comment asking for the imfplay source 8) Yea! This is going great. That was you? lol :D Sorry for the delay, replying to you here made me realize you asked on YouTube :D ...if I converted that for-next main loop to some code that runs every time th...

have you any experience with this? I wrote imfplay, so you could say that, yeah :] this is a barebone version my older QBasic imfplay code, it's kinda garg and undocumented, but it works: CLS DIM VRAM(256) F$ = "imfs\k4t03.imf" SPEED = 1193182 / 560 OUT &H43, &H36 OUT &H40, SP...

I'm very much afraid that it's not without an almost complete rewrite in assembly.

A clean reference for all the game logic and physics is a big help though!

nice work!

That's actually really easy, heh

i.e., does it use adaptive tile refresh? Because if it isn't then this idea is dead in the water anyway. Well some of the platforms have hardware tile support, however compiling just plain C might be less than optimal for 16-bit targets (and should be tried out as a very first step IMO if someone's...

I've once actually finished the entirety of Doom 2 with this mod. Not even mad.

Yup, both!

You always had to sift through a lot of garbage, but hey, that was half of the fun!

Well I think a 7" is more fitting for a rickroll-by-mail :D Got it at an used record store, they always had a box full of 7"s, 10 CZK for one... so I've always bought like 2-3 LPs and then a crapton of singles. When I saw Never Gonna Give You Up, I immediately knew what to do :]] Shame the...
