MiSTer FPGA Forum

I just did a pull request for a quickstart instructions with freedos and ctmouse. Freedos is chosen because of copyright.

Thanks for everything!

Great! Now all that's left is a Hercules garphic module transplant? The "ski or die" game is not running normally yet, and I hope this will be resolved too. Thank you.

have you tried as tandy or cga modes?

We are so lucky of have people with so great skills and patience! kitune-san, spark, Microcorelabs

• Dino Crisis series
• Silent Hill
• Tomb Raider series
• Sentinel Returns
• NFS Road Challenge (aka High Stakes)

OK I cheated because the Tomb Raider series is 5 games and Dino Crisis 2.

Edit: Can I include a sixth? That'd be Oddworld: Abe's Exoddus.

I was shocked when I saw that NFS saga missed the car dashboards in PSX

Now sure if anybody else has tried running/installing Deskmate 3.5 under the Tandy bios, but graphics are really garbled. Almost like its not displaying one or more colors. IIRC there was a graphic mode that was not implemented. I guess deskmate uses it. Edit, from winworld: Deskmate 3, with the exception of 3.04, was designed for use with general...

This was the original topic at vogons

I've found some interesting tests that were linked from vogons for verifying x86 CPu

I guess it's just a matter of compiling them

I had this issue and you need to apply an official patch or install a newer version of this game

A game I have been having trouble with is Castle Master on the PCXT core. I have tried with several different settings. Without EMS or high memory, with EMS and high memory, with PCXT, with Tandy 1000, with Tandy graphics and with CGA graphics. But Castle Master always freezes on the first screen. I tried using Putty to remove into the MiSTer, kil...

I have adapted exact FPGA OPL3 core from Greg Taylor (https://github.com/gtaylormb/opl3_fpga) for MiSTer ao486 core, as I was curious if exact OPL3 is possible within the core. I am throwing here first version of it, there are some errors in conversion to 16-bit 48kHz output stream I am aware of. I tried to be exact, so the core runs on original O...

I have played with it - nice work! One can immediately tell that it is a labor of love. There are so many games and apps to play with, and I have been spending hours with it. One question I do have: I noticed there is some kind of scratchy distortion in most audio. Like if you go and try to play a song in MusicWorks it is easy to notice. But it's ...

Nice :) I have been hoping to see serial mouse support in AO486 because that would help support Settlers 1 and 2 in two player splitscreen mode. So if this works maybe it might be possible to port it to the AO486 core. Not sure who might be capable of doing that though. Probably Sorgelig, but he is usually busy. I have only a little experience wit...

Does any other cores require SRAM?

It won't be required, it's just a compatibility branch

the question is ( sorry if already answered , but couldnt find) how can I easily tranfer files from my windows pc to an hd img file? It's not that straightforward, though I might be missing something. You can use ao486 core on MiSTer plus Dos Navigator or other file manager, and copy from your "normal" vhds (those made for ao486 and moun...

Thanks for your input so far. I had no success with the CBM PC-I, but I got the CBM PC-10 BIOS to boot after padding the file with 32kb of zeros at the beginning: pcxt-pc10.jpg So that was half a success. I learned that this is not a good idea at all and will stop further approaches. :D I tried that bios and I inserted the xtide at the first 12kb,...

you are all incredible

MacPlus had the issue with audio. Lode runner has no FX (laser, ...)

What does Z80 have to do with anything?

It's an emulator written over a z80. There are some issues in github

Ah that explains it then, thanks. Is it in the plans to add them? Dosbox for example reproduces them: https://sourceforge.net/p/dosbox/code-0/3961/tree/dosbox/trunk/src/hardware/dbopl.cpp#l792 Maybe it can be used as a base for implementing them? it's even easier.

working perfectly. Thank you very much

See how many booters! Floppy support will be great.

I think it's best if we try to recruit someone that's capable of modifying the 16-bit IDE module in the ao486 core to work in this core. I'm not sure who that would be though or I probably would have talked to them already. @Flandango / dshadoff /alanswx ? These devs have done some serious work regarding microcomputers and are still more or less a...

The IDE implementation must be compatible with XTIDE Universal BIOS , which is the one currently in use. It is a solid and mature BIOS for this purpose. Isn't XTIDE open source? Maybe it can be expanded to allow a use case for MiSTer with the necessary changes to ease integration? If I understood correctly, the suggestion is to connect one *PC_XT ...

Most games with stable speeds at 4.77Mhz are simple games. Richard Garriott and Roberta Williams would both disagree :D But sure, games would look similar to Apple II or Spectrum games than later 286+ DOS games. If I'm not mistaken the higher speeds only appeared in 1984 with the AT and higher-clocked XT clones (with e.g. a NEC V20 CPU). That's on...

Sorry, maybe I didn't communicate it well. I will try after work. Don't worry, It's probably more my problem, I work more by intuition than by real knowledge in this area.

I think it's not allowed in this forum to post software.
I recommend you creating a raw image in PCem/86Box, write down the cylinders, heads, ... and format is with a valid DOS FDD.

Without any XT experience, learning what's up using 86Box would be a great idea. That emulator is very solid, so if you think you see a bug in the Mister core, make sure to verify the behavior against 86Box. If it fails both places, it's probably operator error. FPGA emulation in general tends to be less polished, and a core that's still being dev...
