Waixing's downloadable NES games (WXN) fall into several types:
  1. Normal NROM, MMC3 or Mapper 164/224 games that work with no problems in emulators;
  2. Waixing RPG games, mapper 176 games that use a protection mechanism not fully emulated that involves playing around with WRAM. Several of these are inexplicably set in GoodNES 3.23b to Mapper 30, which is UNROM-512.;
  3. Attacking, Dark Castle, Galaxy Killer, Little Hacker, Monkey King, Monster Brother, Ping-Pong (Chinese), Tower of Doom, Volleyball: MMC3 games simply with the MMC3 register numbers changed from 0,1,2,3,4,5,6,7 to 5,4,3,2,1,0,6,7;
  4. Five Kids: Normal MMC3 game that uses VT02-style bankswitching in its IRQ handler.
  5. VT03 games.

Type 2 can easily be emulated by adding the protection emulation to Mapper 176 (to be added to the wiki entry). Type 3 requires assigning a new mapper or submapper number however, unless there is an already-assigned mapper that I am not aware of that already implements the MMC3 register numbers changed in the manner described.

mapper 30是两个不同的mapper
在中国mapper 30是WX解密后的MAPPER号(有7年了吧)
在外国mapper 30是UNROM512(fceux强制修改mapper)

在中国mapper 81是mapper 81,Super 12-in-1 EK8B-022 PCB
在外国mapper 81是一个没有发布的游戏。



现在的ines,nes 2.0是非常鸡肋的东西,因为没有标准管理。

这让模拟器非常烦,废除ines mapper number定义,使用UNIF,再完善UNIF,才是王道
