It also acts as a transceiver for the CMS chips. This chip allows the card to be autodetected by programs, since the chips themselves cannot be detected.
However, the CMS and Game Blaster cards have a 40-pin DIP chip labeled CT-1302A. They can also be found on the Creative Sound Blaster 1.0 and can be inserted into sockets on the Sound Blaster 1.5 or 2.0 and a few licensed clones. The sound chips are two Phillips SAA-1099s and they can be found on the Creative Music System Card or the relabeled card, the Creative Game Blaster Card. The only confirmed game is Lode Runner, but the disk image and DOS conversion available on the Internet work fine with a V20.Īlternative : Run game with 8088 or 8086 CPU, use Retrograde Station booter or DOS conversion.Įxplanation : Quite a few games support Creative C/MS or Game Blaster sound. However, the occasional game will not work with a V20 or V30. Due to optimizations in the instruction execution, the addition of a hardware multiplier, the resulting speed improvement could be 15% on average over the equivalent Intel CPU. For systems like the IBM PS/2 Model 25 and 30 and the Tandy 1000SL and SL/2, the socketed 8086 could be replaced with an NEC V30.

A popular, reasonably priced upgrade for these systems was to replace the 8088 CPU for the NEC V20, which is an optimized version of the CPU. Unfortunately, hardware mixing was removed after DOOM v1.2 because there was no room left on the card after the RAM samples for the music had been uploaded and DMA transfers without using the RAM were buggy and inflexible.įeature - Game works with an 8088 or 8086 CPU but not with an NEC V20 or V30Įxplanation : The IBM PC, (many) PCjr., XT, Tandy 1000, 1000EX, SX and HX all have a socketed 8088 CPU.

By using the GUS's hardware, instead of software mixing, typically these games will have better audio performance and higher audio quality. Essentially they boast the best support for the GUS.
Pinball Arcade CD-ROM (Pinball Dreams & Pinball Dreams II)Įxplanation : These games have support for the GUS's hardware mixing capabilities. On these programs, due to the copy protection, it may not work.įeature - Native GUS Hardware Mixing Support Normally, if you were trying to run the program on a non-IBM PC, you would replace BASIC and BASICA with GW-BASIC. The disks could boot without user intervention since they contained the basic DOS files and AUTOEXEC.BAT to start the programs. The above games were created by The Learning Co. With its internally developed software, it usually was not picky. When IBM released software licensed from 3rd party developers, the developers always put copy protection on the disks. With the above games, released by IBM, their disk labels clearly state or should state "Copy Protected".

Other companies may have required you to copy over the appropriate interpreter to avoid having to pay license fees to IBM or Microsoft. The above games were released by IBM, and would contain BASIC or BASICA on the game disk. Games requiring BASIC always came in a DOS-readable format and required BASIC, BASICA or GW-BASIC to function. As clone manufacturers entered the picture, Microsoft combined the Cassette BASIC and BASICA.COM into GW-BASIC.EXE for the clone systems, which did not have BASIC in ROM. These programs were relatively small because they utilized the underlying BASIC in ROM code. However, this version of BASIC was limited to communicating with cassettes, so IBM put BASIC.COM and BASICA.COM on its DOS disks so BASIC could interface with floppy drives. Explanation : IBM's computers contained Cassette BASIC in ROM.
