Re: Possible Tandy regression since 0.74?

Posted on 2013-03-20, 08:13

This would seem to be the inverse of a similar issue with the Pirates! booter and the Tandy machine type, which had a black background instead of blue (sea) in 0.74, but is now blue in SVN. case 0x3d9: vga.tandy.color_select=val; if (vga.mode==M_TANDY2) vga.attr.palette[0xf] = vga.tandy.color_select …

Re: When to use aspect=false?

Well, you can try setting the highest fullresolution= and windowresolution= you can manage coupled with output=openglnb, scaler=none, aspect=true. I think that gives pretty good results with windowresolution=1280x960. The more vertical pixels you give it to work with, the less noticeable the aspect …

Any other way to fix this mode's wide appearance? The blurriness also bothers me. I think you're referring to normal (not tweaked) mode 13h at 320x200, which does need correction if you want proper aspect. You can try output=openglnb which uses irregular sized pixel blocks instead of blurring, but …

One situation is tweaked mode 13h at 320x240 resolution, which has a 1:1 aspect. DOSBox slightly miscalculates its pixel aspect ratio as 0.99 instead of 1.00, which typically causes a slightly blurred appearance with aspect=true that you can avoid with aspect=false, and correction isn't needed with …

Re: Dosbox\win3.11 + mpu401 = impossible ?

What is in the "SB16 Ext MIDI" setup if you click "Edit..." ? I had to create the mapper setup for the MPU401; however, your device driver is apparently different because it's named "Roland MPU-401 MIDI Out Port" in your screenshot, but it's just "Roland MPU-401" with the driver I have. What kind of …

It sounds like you're getting FM music, which is what happens if you chose the "SB16 Ext Synth" option instead of the "SB16 Ext MIDI" mapper setup. The "Synth" options map GM to FM synthesis. What is in your SIERRA.INI file? What port names do you have in the channel drop down list? What you have …

Some needed sfx files are not installed. You can at least get the game to run if you copy the SETUP.PCM file to these files in the PCM subdir: AGUA9.PCM AGUACAE.PCM CARGA.PCM COCHE2.PCM DISPAR00.PCM EXPLOSI2.PCM EXPLOSI3.PCM EXPLOSI6.PCM METRALLA.PCM The sound is a bit repetitive this way, though. …

You can use the MPU401 driver if you want to, but don't expect it to magically sound better than SB16 MIDI output. Add the "Roland MPU-401" driver and configure it for port 330, interrupt 2/9. In the MIDI Mapper, add a setup named "MPU401 Ext MIDI", description "MPU401 Extended MIDI", edit it and on …

Re: DOSShark for DOSbox 0.74

Posted on 2013-03-16, 21:36

I suspect this DOSShark cheat program won't work with a self-compiled (and modified) build of 0.74, anyway, unless your build environment matches very closely to the one used in the official Win32 build (MinGW cross-compiled in Linux, if I'm not mistaken).

Re: Terminator (1990) install help

Posted on 2013-03-16, 21:25

The idea is to create conditions most alike to what the install program and game program were intended to work with on real DOS systems back in the day. You're less likely to run into problems that way. On real DOS systems the A: and B: drive were the floppy drives. Almost all systems had an A: …

It works here with default settings in 0.74. You may or may not need cputype=386_prefetch depending on version of the game, but it should be safe to use even if not necessary. I think your problem is likely how you are installing and running the game. Put the install files for the game into a folder …

Re: DOSShark for DOSbox 0.74

If you get a message in the status window about an exit due to DMA wrapping, that is specific to 0.74. If DMA wrapping is the problem you run into, at what point in the game does it happen? You might be able to work around the problem with loadfix (experiment with various allocation sizes), but 0.73 …
