32X效果比较好的游戏可以秒杀SFC吗。机能可以秒杀SFC吗?
32X
Processor: Two SH2 32-bit RISC processors with a clock speed of 23.011 MHz, approx 20 MIPS each
Video RAM: Two linear framebuffers with support for RLE compression and an overdraw mode to simplify compositing objects with transparency. All scaling, rotation, and 3D operations are performed in software on the SH2 processors.
ROM (BIOS): 3 kb
Color depth: 32,768 simultaneous colors on screen at standard Mega Drive/Genesis resolution. Video output can overlay Mega Drive/Genesis graphics or vice versa. Mega Drive/Genesis video effects such as shadow or highlight do not affect 32X video.
Memory: 256 kB (2 MBit) program RAM and two 128 kB (1 MBit) framebuffers.
Audio: Stereo 10-bit PWM (Pulse Width Modulation) mixing with Mega Drive/Genesis sound for a total of 12 audio channels of varying capability, 20 with the addition of a Mega-CD/Sega CD.
I/O: Same as Mega Drive/Genesis.
Storage: 32X cartridges are fundamentally the same as Mega Drive/Genesis cartridges with some small differences in the plastic casing. A few CD-ROM games were developed that also required a Mega-CD/Sega CD.
Compatibility: Compatible with Mega Drive/Genesis models 1 and 2, JVC Wondermega/X'Eye and the Multi-Mega/CDX. The 32X does not work with the Genesis 3 which lacks some of the necessary interface logic.
Dimensions: 107 × 205 × 110 mm (4.2 × 8.1 × 4.3 in)
Mass: 495 grams (17.5 oz)
