要开发文档？
这些移植游戏除了第一方都是得到授权后自己做的
软件商什么都不用做除非你去找巨硬负责做移植工作的人

你们PS4都没游戏可以玩了？我反正还有一大堆

官方自己设计模拟的系统环境用不着别人授权，游戏是授权兼容不是移植

不兼容也无所谓   反正还有高清复刻

看这里DF的采访文

Across the years, we've only picked up a few titbits on the process - essentially that the original Xbox 360 PowerPC executables are reverse-engineered into an intermediate, then recompiled into x86.

都说了是重新编译的看见了没有
这就是简单移植

Floating point calculations need to be adapted from 40-bit to 32-bit, with potential implications for aspects like collision detection, but Microsoft's aim here is clear - to be able to host game code on their virtualised Xbox 360 and for it to run as close as possible to original hardware.

And then there are the games that previously worked, but didn't work very well. Our early tests of Xbox 360 titles running on Xbox One threw up a host of issues - specifically, areas where the emulator's enforced v-sync could see games that ran at 30fps drop down to 20fps. And then there was Halo Reach, a flagship title of crucial importance to the backwards compatibility programme that just didn't come up to the required standard. It proved to be the catalyst that saw Microsoft revisit its testing procedures, leading to existing back-compat titles being revamped with improved performance.

"Yeah, we absolutely did [that] and take some credit for it, actually. It was the review of Reach that sort of put us on the spot. Basically, what happened when we first started doing these games, we got things to run and because we were able to emulate the 360 on the One, we were quite pleased with ourselves and so we started pushing out games and a lot of our testing was subjective," Stillwell explains.

你不是一键移植吗，读一遍再回复我，重点我都给你标出来了

这都需要一一针对某个游戏调整了还要改变其原始数据所以才要重新下载
也就是说有可能连引擎都要修改如果是第三方游戏这还要第三方同意才行
它都已经反编译为X86可执行的指令了还谈何模拟器
模拟器是直接可以在异构硬体上运行异构的专用指令集
一键移植的确是太夸张了但这绝不是单纯的模拟器因为XBO的性能就在这里摆着

你是看不懂英文还是装糊涂？ 通篇不断的提到测试，在XONE上模拟360，改进360模拟的性能，到你这不是模拟了？

你的意思是模拟器不需要编译？编译的东西就不是模拟器了？
