On the S7 (Exynos, not Snapdragon), even Diablo 2 and Commandos run fine. There are quite a lot of old treasures waiting to be replayed. ?

Yeah, me too. ?

Not quite sure atm, there were some changes recently. You can try cputype=pentium_slow, or pentium_mmx.
These are my cpu settings, working e.g with Commandos, Diablo 2, or Half-Life:

[cpu]
core=dynamic
cputype=pentium_slow
cycles=max 105%
cycleup=500
cycledown=500
isapnpbios=true

Seems your Win95 desktop is still set to 8bit (256 colours) mode. Change it to 16bit (65k colours), that should fix at least some of these games.

That’s what’s happening for me, too. Maybe it either needs to be implemented, or it doesn’t work on Android. We need dev support on this one… 🙂

To be fair, the Mali is considerable weaker than the Adreno chip, but it’s still quite good. For 3D games on the phone, I’d suggest you use Game Tuner anyway, to reduce the resolution to 1080p, or even 720p. Saves battery, and doubles or even triples the 3D performance. I’d say the Adreno is even too powerful, and you don’t really need it.

Plus, it’s not fully compatible with GLTools. For example, you can’t do this with a Snapdragon, only with Exynos/Mali: https://youtu.be/-3YGKDlSG2U

Have you tried the mixer command? https://www.dosbox.com/wiki/MIXER

I haven’t managed to get it to work properly, but maybe I’m missing something.

Yes, you can emulate whatever your device is capable of.
But don’t expect too much from the Snapdragon 805. I’ve got an old Note 4 with SD 805, and the best I can get is something between a P75 and a P90. Snapdragons are bad when it comes to emulators in general, and Dosbox in particular. It’s something Qualcomm did to the cpu structure, so it simply doesn’t show the performance you’d expect from a 2.7 GHz device.

The Exynos 8890 in my S7 edge (2.6 GHz) is almost 3x as fast. Depending on the benchmark used, it emulates something between a Pentium MMX 233 MHz and an AMD K6 333 MHz. It can run Doom with up to ~130.000 cycles, for example, while the Note 4 couldn’t do more than ~50.000.

I’ve recorded a comparison benchmark, both devices running full speed, with performance governor enabled: https://youtu.be/Lwt6qjveiT0

Doesn’t make any sense atm. 3dfx-only games are so advanced, you would get framerates of about 1-2 fps. Tomb Raider for example runs MUCH faster in SVGA, than in 3dfx, where it’s absolutely unplayable. So later games would run even worse.

[Al ex]

There’s no glide support in Magic Dosbox yet, so I believe it’s a placebo effect. Dosbox Turbo has rudimentary 3dfx support, but it’s so incredibly slow, you’re better off using SVGA. Let alone the crappy sound emulation and other bugs in DTurbo.

The problem is that there is no Glide wrapper for Android yet, so the whole 3dfx/Glide code has to be sofware rendered, and is not executed natively on the gpu. That’s why it’s completely useless atm.

I would so love to play Tomb Raider or Quake in 3dfx, and I had lenghty discussions on the matter with Tony (Magic Dosbx dev). But there simply is no way for proper 3dfx emulation yet, unless someone comes up with a Glide wrapper. 🙁

and device temp

Lol, yeah. Be thankful you’re not on a Snapdragon S7, it would either melt or explode. 😉

[Al ex]

Looks good. ?

It’s only accessible via expert settings, because it’s a highly experimental tweak, that can cause nasty sound issues. That’s precisely what expert settings are for.

Btw, if you set even higher values, they’ll be ignored, and cycles=max will be used.

[Al ex]

You can go up to 120% since the last version. Might cause sound issues in some ganes, but it’s worth a try. 🙂

[Al ex]

Thanks, glad you like them. Initially, I was just testing out Samsung’s cool recording feature. Should make some more in the future. 😉

[Al ex]

It works just as it does on the PC version of Dosbox. You need to activate Expert settings, chose the correct core settings and set the proper mounting commands (the “extSdCard” path below is an old setting, Samsung changed it to weird number codes in Marshmallow), and that’s about it:

[cpu]
cputype=pentium_slow
cycles=auto max 110%
cycleup=500
cycledown=500
isapnpbios=true

[autoexec]
