*DOS* Fellow problems with my Athlon TB box

andreas · 16 January 2002, 08:19

Hi.

Just to test a game similar to the one Galahad discovered as a dirty hack using hardwired JMPs, I fired up good ol' Fellow DOS 0.3.2a on my Win2k box, Athlon TB 1.333 GHz, because this emulator version has always been invaluable for games with " broken" code.
But what did I see?
SPEED FASTER THAN A ROCKET ...

I tried with every setting imaginable but absolutely neither any intro nor demo were playable. Everything ran as if you had switched to WARP mode in VICE [C64 emulator]...

I set sound to "Emulated, no sound output" because I cannot get sound yet with Win2k.
Seems I have to install another Windows (9x) to get a reasonably SLOW speed again...
BTW: Does DOS Fellow work on XP, actually?

Is your Win2k on NTFS ??? Cause I noticed the same issue on Win NT4 and NTFS, so I guess it´s a filesystem thing ! My friend got Win 2k installed on Fat32 and Fellow (DOS) runs at normal Speed on a 1,7GHz. P4 !!

I also recommand to everyone to jump back to FAT32 for speed performance. (if you did'nt use security folders or files > 2Go)

Why not jump then back to win9x if performance is everything ?

Seriously, I like NTFS because it is journaled. No need for loooong chkdsk if system crashes because of too big overclocking attempts or something similar

@RetroMan:
Everything but NTFS.
C:\ is FAT (not FAT32 in order to access the C: partition using any boot disk if something screws up completely), the F: Disk (where my DOS Fellow resides) is FAT32.
No NTFS...but still lunatic speed.

Go here : http://www.hpaa.com/moslo/ and download the MOSLO util !! With that one you can clock down your system with software untill 4,77Mhz

No joke ..... I just tested it on a Win2k computer and it works really well, you just need to find the optimal settings for your system to run fellow (DOS) smoothly

Yes that app has been around for a while, of course it was mainly used to get older MS-DOS apps to run on faster 386/486 boxes at the time these were written to run on an old XT box.

Also maybe somebody knows this for sure, but isn't this app basically a NO-OP type of program? One that adds a bunch of no-op's to delay the CPU cycles. Just wondering is all

RetroMan · 17 January 2002, 00:31

I guess it´s working like that, mainly because only the game (or emu) itself is affected, if you switch to Win with Alt-Tab for example, it´s the normal CPU speed ....

I tried Mo'slo before. It's mostly ok but sometimes it cannot keep the same speed and get too fast for a few moments.

This page has some similar programs:

I prefer turbo because it a windows application.

I think "Emulated, no sound output" is the problem. If you use WinUAE and disable the sound emulation, it runs to fast, too.

Not always.
"Disabled but emulated" and "Disabled" isn't the same thing (I hope).
