miker Posted May 15, 2010 Share Posted May 15, 2010 Hi! Pardon my ignorance (if any), but could someone point me to some Doom engine, so I can shoote'm a bit without watching a slideshow. Thanks! P.S. Have only 14M of RAM, no accelerators nor FPUs. Quote Link to comment Share on other sites More sharing options...
urborg Posted May 16, 2010 Share Posted May 16, 2010 Maybe try out "Substation". This is STE/Falcon game. Here is a description of the game: http://www.mobygames.com/game/atari-st/substation and some screenshots: http://www.mobygames.com/game/atari-st/substation/screenshots Quote Link to comment Share on other sites More sharing options...
Christos Posted May 16, 2010 Share Posted May 16, 2010 Running isn't a slideshow if you put everything on low. Quote Link to comment Share on other sites More sharing options...
miker Posted May 16, 2010 Author Share Posted May 16, 2010 Yeah, I liked Substation, and may try someday again. Running also works fine. I just asked if someone tried to set up pmdoom (for example - as it looks the most complete port) to run it fine on "un-boosted" machine. Thanks anyway!

Christos Posted May 16, 2010 Share Posted May 16, 2010 Right, if you turn off audio it's kind of playable. Bad mood was faster but afaik it wasn't fully playable My advice would be to avoid fps on an atari. 1 Quote Link to comment Share on other sites More sharing options...
+poobah Posted May 16, 2010 Share Posted May 16, 2010 Running isn't a slideshow if you put everything on low. Because a slide show is faster? Seriously tho, Running on a stock Falcon isn't a lot of fun. Quote Link to comment Share on other sites More sharing options...
viking272 Posted January 23, 2014 Share Posted January 23, 2014 Not sure if you're still interested in a Doom Hi!Pardon my ignorance (if any), but could someone point me to some Doom engine, so I can shoote'm a bit without watching a slideshow. Thanks!P.S. Have only 14M of RAM, no accelerators nor FPUs. Not sure if you're still interested in a Doom engine, but BadMooD has been released for the Falcon now. It's an alpha release, v02 was out the other night. It's fully playable Doom and runs at a decent frame rate, quite an achievement for a 14MB unaccelerated Falcon. See the official site for more info and a download link: http://devilsdoorbell.com 1 Quote Link to comment Share on other sites More sharing options...
viking272 Posted January 24, 2014 Share Posted January 24, 2014 If you have CT63 installed (e.g. 68060 CPU) an alpha version of BadMooD has been released. See the binary downloads menu on the website: http://devilsdoorbell.com Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted January 26, 2014 Share Posted January 26, 2014 Go get (run, don't walk) Doug Little's new Bad Mood (alpha) release, as mentioned above. It's freakin' awesome! PS Just keep in mind it is a work in development. Quote Link to comment Share on other sites More sharing options...
oky2000 Posted September 26, 2014 Share Posted September 26, 2014 Do the Falcon version use DSP for co-processor? Quote Link to comment Share on other sites More sharing options...

See the binary downloads menu on the website: http://devilsdoorbell.com If they're going to support the CT63, why not through in support for a 68882 on a "stock" Falcon?

dml Posted September 27, 2014 Share Posted September 27, 2014 68882 support was implemented some time ago, but the main benefit of the chip is precision - not speed - So the DSP outperforms it for all the jobs which are needed for that engine. It is still used for the internal profiler which is used to assist with optimizing the engine, but no longer used by the engine itself. Keeping it in the engine just prevents it from running on a Falcon without 68882 (and making it switchable offers no benefit). (FPU will likely be needed for my next project, which is different in nature from Doom - which was always designed for a 16/32 integer machine) 2 Quote Link to comment Share on other sites More sharing options...

I just like to see 68882 support whenever possible since at this point it's a $20 upgrade and if it can help in any way lighten the load off the CPU or DSP, then by all means.

I have identified use cases for the chip in realtime 3D which can't be handled easily by the CPU or DSP, and will be making extensive use of it soon. It's pretty useless to try to accelerate simple 3D math using FPU but it does have its place for more subtle cases. Just hasn't been exploited much yet on Ataris - not to my knowledge. 2 Quote Link to comment Share on other sites More sharing options...

Ain't that the truth! And the same goes for the 68881 before it too! Quite the shame since the PC market always made use of their FPUs long prior to the merging of CPU and FPU with the Pentium [or the 68040 on the Motorola side of things]. I'm actually surprised Atari Inc didn't create an FPU for their 8-Bit computers; they made practically everything else!
