From the software side, the 65C02 adds a couple of new instructions and modifies the behaviour of some existing ones. The 65C02 is another modified version of the MOS 6502 made by Western Design Center, it’s a lot more efficient due to its manufacturing approach (CMOS). That being said, what does all of this mean for the programmer?īefore we start, we’ve already covered some parts of the MOS 6502 in the NES article and also described a 16-bit variant made by WDC and Ricoh in the SNES one, in case you want to check them out first. After checking out the official docs, it does seem to replicate a lot of behaviour from the famous MOS 6502 and WDC’s 65C02. The HuC6280 is not an off-the-shelf component, like the Z80, but instead a proprietary CPU designed by NEC. One of them is the CPU, which can operate at two speeds: ~1.79 MHz and ~7.16 MHz. Inside this console, we find the HuC6280, a chip made by Hudson Soft that houses two components. This article will focus on the PC Engine/TurboGrafx-16, but will also discuss the expansions that led to the release of the PC Engine Duo/TurboDuo.

PC Engine Duo/TurboDuo: A combination of the PC Engine/TurboGrafx and the aftermarket CD-ROM² expansion.Its exclusive features are out of the scope of this article. Supergrafx: Enhanced version of the PC Engine with a completely different case and new hardware.

Reminds me of the NES/Famicom adaptation. It has the same features with a different external appearance.
