These are versions of DOSbox, pulled from the SVN on 4/3/2018, "gimmicked" to remove the 8x14 font from the VGA ROM BIOS. The purpose of this is to replicate the behavior on all roughly-post-1995 video cards, wherein the 8x14 font pointer in ROM is directed to the 8x16 font, producing garbage text. This decision was made by VESA. The ideal way to test this issue and its fix is to acquire the FIX8X14 utility package, which you can find in this directory, or from the original website at http://www.bttr-software.de/products/fix8x14/ You can manually replicate this behavior by selecting screen mode 9 (EGA 640x350 @ 16 colors) in e.g. QuickBasic and attempting to print some text. The files ending _dup are versions in which I copied the 8x16 font over the location of the 8x14 font, meaning that the pointers ARE unique but the problem will still occur. This results in DIAG8X14.EXE failing to identify the problem though it WILL still produce the error on its test screen. FIX8X14.EXE will still fix the issue. The code change to accomplish this was in src\ints\int10.cpp, starting line 548, where the definition of int10_font_14 is commented out and the code following the comment block redefines it as a 256 * 16 block identical to the 8x16 font. The other files ending _8x14 are versions which replicate the issue more accurately. The memory pointer is identical for both fonts, so DIAG8X14 will identify the issue. FIX8X14.EXE will of course fix the issue. The code change to accomplish this is in src\ints\int10.cpp, lines 280 and 281, changing int10.rom.font_14 to int10.rom.font_16. The changes from the _dup version are still included but could be backed out by removing the added code and uncommenting the int10_font_14 block. The various JPGs show the failure mode and output of DIAG8X14.EXE; the fixed versions are self-explanatory. The game is MICE MEN by Soleau Software.
