Is this Warcraft II for Mac? If yes then DosBox cannot help you. Plus DosBox is basically DOS and in DOS (unlike Windows 95+ or MacOS) file names are 8.3 so the names will be truncated.

Friendly advice: I'd obscure vehicle plates before posting images on the net. Because it's ok for all the other people on road to see your plates but not the people online. Because people on the road do not know your interests, your job, your hobbies and what computers you have home and cannot make …
Re: STALKER (The Movie) Restoration Trailer Released!

Oh man thank you for that! Stalker is a great movie. In fact all Tarkovsky's movies are great. My favourite by far though is Andrei Rublev. I've also seen this a while ago: http://www.openculture.com/2010/07/tarkovksy.html EDIT: just saw the trailer, it sent chills up my spine!

This Amstrad CPC demo (Logon's Run, by Overflow / Logon System) is pretty amazing and probably blows away Overdrive 2 out of getting the unexpected out of a hardware platform: https://www.youtube.com/watch?v=pmlUYW8bBLY That is...impressive. Congratulations to the authors, they deserve the cheers. …

It just means I need to re-visit my timings. I did not have much time recently between my job, travel and kids 🙁

While working to finish Dragon Quest VIII I have started playing Mass Effect 4 (on the PS4). I must say I like this game so far. I am a big fan of Mass Effect games (having finished ME2 twice, and half way through the 3rd playthrough, and ME3 once).

Post on VCF forums (http://www.vcfed.org/forum/forum.php). Based on the date, it does not seem to be a S-100 based computer (not tall enough). Are you sure it is a computer at all? It could be a telex machine (giving the telephone and the printer)
Re: Do you remember how/when you began your Collection ?
Posted on 2017-04-12, 17:06
When I started my job at Apple and they told us about Apple ][ and Macintosh is what drove me over the edge to actually start collecting. Many years later I have the collection in my signature.
Re: Playing Windows 95 Games on Windows 10 Through Emulation
Posted on 2017-04-12, 15:13
None of the cores is at 100%, all 4 are between 20-30% The only other thing I can think of (from personal experience with writing emulators) is just a lot of locks/waits which when used at higher frequencies, they show more and more and become a bottleneck. But it is just a guess, I could be wrong. …

I got this from the Cupertino, CA flea market: an ATI Radeon 9000 (with fan broken) a S3Trio 64 DX (without metal bit) and a MSX joystick. The 2 cards cost me $3.
Re: UniPCemu cycle accurate 8088 implementation

If the immediate takes 1 cycle in those given timings, then what about the modr/m parameters? Since a modr/m parameter has variable length(1-3 fetches/cycles)? The problem we're faced next is: how did Intel arrive at the given timings in their manual? If we knew that, much, if not all, EU timings …
Re: UniPCemu cycle accurate 8088 implementation
Posted on 2017-04-09, 15:47
It is and it is not wrong. For example "acc, imm" and 'reg,imm" while they say 4 the execution is really 3 because you spend 1 cycle for fetching the immediate from the prefetch queue. For the other ones, I do not remember what my reasoning was, but it does seem 3 might be wrong.

Do BIU cycles still continue during execution phase of the EU? Yes. If nothing else the BIU will be busy prefetching from CS:IP. If you mean does the CPU execute some part of the instruction while it is waiting for the BIU to do some work I do not know about that. I work under the assumption that …

Dragon Quest VIII remake on 3DS. I did not finish when it came out the first time on PS2 so this is my chance to do it now. I am enjoying it a lot. Already 30 hours in, but I think I have to put about 60 more at least.
Re: x86 prefetching and larger immediate parameters?
Posted on 2017-04-06, 15:24
Does the CPU start this at the very first cycle of your emulator's version execution phase(and real CPU), to check for zero divider or isn't there some small checking time/delay after reading all neccesary information to start calulating(register/memory contents and/or divider)? I assume not, since …
Re: x86 prefetching and larger immediate parameters?
Posted on 2017-04-05, 23:01
If a DIV by 0 exception happens then the following things occur: 1) the EU goes back to its initial phase which is EU_PHASE_DECODE 2) then I in there I check if there is a exception (which is the same workflow as described in the 8088 datasheet from Intel, I've basically implemented that diagram) 3) …
