RedMSX 1.4

by MSX Resource Center on 21-04-2005, 00:00

RedMSX is a Brazilian MSX emulator based on blueMSX 1.0.5. The emulator comes with a simple, easy to use GUI that offers all the features a novice MSX gamer could wish for. One of the most interesting things we noticed while testing the emulator is that it uses a lot less CPU load than all the other emulators in this test. This could make RedMSX particularly interesting for people who don't have the latest generation of Windows PCs.  


One of the downsides of RedMSX is that, as with fMSX, the user has to switch between PAL and NTSC mode manually. Sometimes some tests didn't appear to run as smooth as they should, which turned out to be caused by the wrong PAL/NTSC setting. Lets hope future versions of RedMSX will offer auto-detection of PAL/NTSC mode as well.  


As of version 1.4, RedMSX is also capable of emulating the Sega Lightgun, which is a feature no other MSX emulator currently has to offer. Karoshi Corporation's MSX port of Duck Hunt needs such a lightgun in order to function.  




Although blueMSX currently tops the EmuRank Charts, things were different at the time RedMSX borrowed its main code from blueMSX. This becomes clear with most of the tests, as only a few run without any glitch whatsoever. In fact, Avaakkus and Bombaman were the only titles in which we could not detect any errors. There were a few minor glitches in Aleste 2, SD-Snatcher, Turnix, Vscreen and the Woei demo that were not particularly disturbing, but -as expected- megademo's such as Almost Real, Metal Limit, Relax and Unknown Reality gave RedMSX a really hard time. The 20th aniversary demo did not came any further than the Abyss logo, while TNI's Bounce demo even made the emulator hang, right after showing a garbled Bounce! logo. Sphere only showed a bit of Plasma instead of the infinite logo, and then came to a halt.  




In general, the audio quality of RedMSX does not impress. The output is very soft, and could do with a little less bass. The PSG often cracks and squeeks while the SCC often does not sound as full and sharp as the real thing. As for the MSX-MUSIC, the main problem are the drums, which don't come close to sounding like the real thing. The basic FM tones do sound fairly nice yet, way too soft. Boosting the volume of every soundchip would greatly improve the audio-experience of this emulator.  




In a way, RedMSX shows what tremendous progress the blueMSX team have made since. The main difference between RedMSX and blueMSX at the time was the way the emulators handled ZIP files. Now, blueMSX tops the EmuRank Charts with high marks on accuracy, features, useability and audio quality. Especially on the latter, RedMSX still has a lot to gain. The emulator does, however, perform well enough to run most regular MSX games and as it uses very little CPU load, this emulator might certainly be worth checking out for people who don't have a high-end setup.
