In what kind of computer? If the computer has no pull-up resistors on the ISA bus, the documented "port 388 returns 06" check will not work correctly.

And because it was so much fun, the same procedure for the CM-32L: v1.00 to v1.01: Version 1.01 cures the following problems: In Patch Temporary Area, when MIDI Exclusive Data (8 different parts and a rhythm part) is sent, "tone" and "bender range" to be varied do not change. With 2-byte-message, …

Re: Patches for 768 KiB Tandy 1000s

The same for "Ultima V: Warriors of Destiny". Replace the "T1K.DRV" file that comes with the game with the attached one to run the game in Tandy 1000 graphics mode even on a 768 KiB Tandy 1000 system.
Patches for 768 KiB Tandy 1000s
Posted on 2019-12-14, 19:41
The Tandy 1000 TX, TL and RL can be expanded to 768 KiB. This means that there will be 640 KiB of conventional memory, undisturbed by video memory, which gets its own 128 KiB. This would be the ideal configuration, were it not for the fact that a few games do not work on such a system, as they …

I have succeeded at patching Privateer to no longer ignore the music device's port address. The patches are as follows: For the original floppy disk version of Privateer: PRIVATER.EXE, original CRC32 91FA6816 Change the three bytes of hexadecimal file offset 00071EB1 from 66 6A FF to FF 76 08. For …

If AL is 00, then CX:DX is "a signed offset from the start of the file", or in other words, an absolute offset. 😀

I am not sure why you need a signed offset. Here is how I would do it: .model tiny .data filename byte "SOUND.TRE", 0 patchPosition dword 0A98F1Eh patchData word 0320h .code .startup mov ax, 3D02h ; open file for read/write access mov dx, offset filename int 21h jc fail mov bx, ax mov ax, 4200h ; …

What exactly are you trying to do? You don't need to read an entire file into memory, change two bytes, then write back the entire file. All you need is to seek to the patch location and write the changed two bytes? Probably it is easier to code a TSR to redirect the 330h writes to other port. No, …

It is a known bug in Privateer that it blatantly ignores the "sound.cfg" settings for the music driver. (At least known to me, now known to you. :)) If you have the floppy disk version, you can open the file SOUND.TRE in a hex editor, search for the string "Roland MT-32" (yes, the game uses an MT-32 …
