这里是下面链接到它的一些匿名的内部功能，似乎每个开关2个数组索引的JavaScript代码，他们似乎还有些太超值了，但我不知道在哪里，他们都回到memoryReadJumpCompile()函数或这两个数组指数的。
他们很有可能将reuturning实际数组索引和函数名编译似乎每次你打电话任何这些数组索引，他们将重新评估与它们相关的一些新的结果的功能仍然不知道在哪里，结果是存储如果实际指数的保持功能，我最好的猜测是实际的数组索引就像函数名和它们是由另一段代码，其中前所未有其他指数的被地方称为代码，但可以说，前2个例数组索引返回。
this.memoryHighReader[0] = this.memoryReader[0xFF00]
因此，他们都成为了同样的事情，我发现，它就会在指令执行器进行处理，像这样
case 242:
a.registerA = a.memoryHighReader[a.registerC](a, a.registerC);
break;
GameBoyCore.prototype.memoryReadJumpCompile = function () {
//...
else if (index >= 0xFF00) {
switch (index) {
case 0xFF00:
//JOYPAD:
this.memoryHighReader[0] = this.memoryReader[0xFF00] = function (parentObj, address) {
return 0xC0 | parentObj.memory[0xFF00]; //Top nibble returns as set.
}
break;
case 0xFF01:
//SB
this.memoryHighReader[0x01] = this.memoryReader[0xFF01] = function (parentObj, address) {
return (parentObj.memory[0xFF02] < 0x80) ? parentObj.memory[0xFF01] : 0xFF;
}
break;
case 0xFF02:
//SC
if (this.cGBC) {
this.memoryHighReader[0x02] = this.memoryReader[0xFF02] = function (parentObj, address) {
return ((parentObj.serialTimer <= 0) ? 0x7C : 0xFC) | parentObj.memory[0xFF02];
}
}
else {
this.memoryHighReader[0x02] = this.memoryReader[0xFF02] = function (parentObj, address) {
return ((parentObj.serialTimer <= 0) ? 0x7E : 0xFE) | parentObj.memory[0xFF02];
}
}
break;
}
}
以上的JavaScript几乎像Java，但我不明白如何将转换function(parentObj, address) {...}在memoryReadJumpCompile什么最简单的方法将其转换为Java，而无需使用任何接口。 我想用一个switch()
以下是我迄今为止在Java中（因为我用精缩JavaScript版本时，我开始将它不使用十六进制字母）
