Re: Retro Software Development?

Somehow this example list is all about products, mostly completed or aimed to alter/adjust already existing, mixing hardware production and software announcements. It's not the retro software development talks. What if I want to develop a new game, or game engine for DOS, but looking from the …

Re: Trident tvga9000 -1 rom?

Dumped the Bios from my TVGA9000i-2, not sure if that -1/-2 revision is critical, the version name is the same D4.01E as from file from VGA museum. Filename Trident 9000i-2 Ver. D4.01E.bin.zip File size 20.18 KiB Downloads 4 downloads Filename Trident 9000i-2.jpg File size 1.15 MiB Views 181 views

Re: Trident tvga9000 -1 rom?

I keep getting an device id error. Im not sure what to select in the software. As there is no TMS option. You can uncheck the "Check ID" checkbox in the Options group (bottom left part of the Xgpro app) and retry, reading should work the same for any pin-compatible EPROMs, any 27256 chip will do …

Re: Game environments that left a lasting impression

in Milliways
For me it's Anachronox . The great storytelling, music, voice acting, locations carrying emotional imprint. Some in-world elements (architecture or furniture designs) are so reasonable and natural you'd wonder why something like this does not exist yet in the real world. I was not accustomed to …

Re: Retro Software Development?

From what I understand from Hamby, this new section should be about programmers talking about programming new stuff for new old machines. No release announcements. This. It's not about specific product development and support. It's not about tutoring the caste of noobs by the caste of mentors ( …

Re: De-noising and capacitors

in Milliways
I vaguely remember that the factor must be 1,41 for the DC input voltage. Was somehow related to peek envelope something ? So for exampl, a digital IC running at 5V DC needs a decoupling capacitor, intended for filtering, (say bipolar, 100 nF) that can handle at least ~7V AC ? The 1.4 coefficient …

Re: De-noising and capacitors

in Milliways
That's all fine so far, but I remember that it is even better to add two more caps: 100 Nanofarad(s) and 10 Nanofarad(s) . In addition to the 1000 Nanofarad(s) (1 Microfarad).. Now I wonder, since these values weren't mentioned by that operator back then - are there further values or filtering …

Re: Game Sound/Video Stuttering in pure DOS, but running fine in Win98. Is it a driver / software configuration issue?

I don't know if I have combine cache mode enabled in DOS. I've never had to manually enable anything like this before The Write Combine mode appeared starting with Pentium Pro CPU, it's related to Memory Type Range Registers: https://en.wikipedia.org/wiki/Memory_type_range_register . This is not …

Re: Game Sound/Video Stuttering in pure DOS, but running fine in Win98. Is it a driver / software configuration issue?

Another hint. Do you have write combine cache mode enabled for the framebuffer while playing in DOS? I don't know if your card's bios enables it when entering VESA modes in DOS, Windows drivers did that for sure. I remember UNIVBE did enable write combining for my i740, the frame rate becomes …

Re: Why does the order how Object files are added to a library with wlib change the performance of the executable?

The disassembly code of each object file/code is the same. Thus there is only the linker as variable option. Don't look into object files, look at the whole executable, after the linker did its job. The wait function should be everywhere the same, only the position in the EXE might be different. …

Re: Why does the order how Object files are added to a library with wlib change the performance of the executable?

What's the platform you're running it on? It could be anything - different alignment, or cache-friendly layout of the code. It would be good if you looked into the disassembly of the final executable to see the difference. Linker does not know the external conditions, so has no information on how to …
