当年PS的硬件指标都比CPS1、CPS2、NEOGEO强吧，为啥移植2D格斗游戏老缩水？

Main CPU: MC68000 @ 12MHz
Sound CPU: Z80 @ 4MHz
Sound hardware: YM2610 @ 8MHz
Sound Capability: Stereo up to 56KHz, 4 channels FM (4 operators + LFO) + 3 PSG + 1 noise + 7 4-bit ADPCM
Video hardware: 2 palette banks with 4096 (15-bit) colours each. Simple (4-bit) tile layer + 380 zoomable, linkable sprite-strips. Sprite-strips consist of upto 32 16x16 (4-bit) tiles each.
Resolution: 320x224.
Main RAM: 64KB
Sound RAM: 2KB
Video RAM: 128KB (only 68KB is used)
Main ROM: 128KB on-board (BIOS) + upto 8MB on cartridges
Sound ROM: 128KB on-board (only less then 32KB used) + upto 512KB on cartridges
Sprite ROM: up to 64MB
Tile ROM: 128KB on-board + 128KB on cartridges, later cartridges use a portion of sprite ROM that can be larger.
Sound ROM: up to 16MB
Backup RAM: 64KB
Clock/calender: NEC uPD4990a
Memory Cards: JEIDA 3.0 compliant.

以上NG的硬件资料，它的主内存194KB,可见其内存并不大，但我觉得它的媒体是卡带，画面和机板潜力挖掘提升很大部分是靠了后期大容量的卡带。
