Re: TEXT font size

Maybe all you want to do is load a 15-line font, but that doesn't change the emulated display dimensions to 320x240; there will still be active screen area beyond the right and bottom edges of your 320x240 viewport. If you just want the font, get the PC Mag FONTEDIT program available here: ftp://ftp …

Re: TEXT font size

What kind of system is this? DOSBox for phones and the like should use the native 320x240 resolution of the display, but with whatever you're using it's showing the scaler pixel doubling. Double-height and double-width create a normal VGA refresh rate for a 320x240 resolution. You could change the …

Re: TEXT font size

The attached TSR program sets up a 320x240 native resolution with an 8x15 font, yielding a 40x16 text display. Mode 1 is used as a base because the horizontal parameters are already in place, so only the vertical must be adjusted. The display is double-width and double-height to create a typical 60 …

Re: TEXT font size

A 320x240 text display? Only tweaked VGA graphics modes have that exact resolution. Using machine=cga with mode 0 or 1 text (40 column) has a native 320x200 resolution, but still with 25 rows. Many DOS programs expect 25 rows, anyway, and won't adapt to fewer. What is this for, some hand-held …

Re: CGA Composite Mode under DOSBOX?

Looking at the PCjr BIOS disassembly for function 0Bh of INT 10h at offset E543h in the ROM, the first instructions are "MOV DX,3DAH / IN AL,DX" so my .diff patch is correct according to the BIOS. However, DOSBox SVN is doing exactly what the PCjr BIOS does regarding the palette entries. Palette 1 …

Re: CGA Composite Mode under DOSBOX?

You can see the reason for the mixed intensity of palette 1 in the INT10_SetColorSelect() function (the one changed in the above patch), where it's using entries 3, 5, 0xf . You can change the entries for both palette 0 and 1 to all intense colors with: case M_TANDY4: for(Bit8u i = 0x11; i < 0x14; …

Re: CGA Composite Mode under DOSBOX?

Below The Root works with machine=pcjr in official releases, but has a problem in SVN when the game calls INT 10h/AH=0Bh/BH=08h/BL=00h. BH=08h is a strange subfunction number, but DOSBox treats it the same as BH=01h, thus selecting palette 0. There appears to be a bug in INT10_SetColorSelect(). I've …

Re: Fatman: The Caped Consumer

It's indeed strange that the developers of the game felt the need to mess around with the keyboard hardware in unusual ways... never heard of any other DOS game that does this. Anyway, here is a Win32 build of 0.74 with the patch applied. The game seems to work fine with it using default settings.
