Dosbox on raspberry pi2/1/2024 ![]() They all run fast enough to play their games, unlike DOSBox, which on the XBox runs at the speed of about a fast 386. It's the same with the XBox (the original XBox, not the XBox 360) - the XBox has a P3-733 Mhz CPU, and there are a lot of great emulators ported for it, such as SNES/Megadrive/MAME/Atari ST/ZX Spectrum/C64/NES/etc. I couldn't see any difference between the two in terms of DOSBox performance, however, this could be due to the SDL/directfb issue. Second question, does DOSBox use much floating-point arithmetic? There are two Linux builds for the RasPi, one that's complete but only has software floating-point support, and one that's incomplete but has hardware floating-point support. ![]() I mention this, because both packages use SDL., and at the moment the RasPi only supports SDL via software-rendered directfb.ĭo you reckon that performance will improve, if SDL could be made to output using some GPU accelerated method, perhaps thru OpenGL ES? ![]() I also tried ScummVM, and experience the same issue, your character can move just fine, but if the view pans, things get sad. But if you try to start running through the stage, the framerate takes a dive, and CPU usage hits 100%. If Keen is moving around, firing off his raygun, everything is sweet. until the screen starts panning, then the framerate stutters. It's sporting a 700MHz ARMv6, which I thought would be enough to run Commander Keen 4 at full speed. First I tried 0.74, then CVS, both compiled from tarballs. Of course the first thing I tried was DOSBox. Moreover, the current version of Dosbian lets you generate floppy disks and hard disk storage designed for a capacity of up to 2GB.So I'm one of the lucky ones that got his Raspberry Pi embedded Linux system last week. The operating system automatically emulates the required legacy hardware, such as sound cards and network and graphics cards, and it allocates memory resources to match. ![]() The Dosbian developers do not list any further requirements. However, for old Windows games to run well on Dosbian, a Raspberry Pi 4 with added RAM is recommended because the software for these games requires fairly extensive memory capacities. All of the more recent generations of the small-board computer (SBC) will support Dosbian without problem. The operating system can be used on a Raspberry Pi 2B, although some modifications of the configuration are required to run games smoothly. Paired with Dosbian, a development by Italian programmer Carmelo Maiolino, you get a mature and easy-to-deploy solution.ĭosbian on the Raspberry Pi does not take much in terms of resources. DOS runtime environments and DOS emulators such as DOSEMU and DOSBox often require a complex setup on Linux to run old DOS games.īecause older computer systems that are still suitable for the 16-bit operating system from the 1980s and early 1990s are becoming increasingly rare, the Raspberry Pi is a great alternative platform for the old games. The installation will typically fail, the hardware is far too fast, and the systems no longer support numerous components such as Soundblaster 16 sound cards or floppy drives. Of course, state-of-the-art PCs are not much use for installing games for the old 16-bit operating system. Many users still hold old DOS games dear despite, or maybe precisely because of, their blocky graphics, beeping sounds, and chiptune music.
