You try. I just downloaded it. There are instructions in it. This is complete. Only half of the text was downloaded before. This can be used after decompression without using a virtual CD-ROM drive, but it also has some minor defects. For example, some words on the menu are not displayed, but in fact the effect is very good. There is no lack of content. Looking for it for a long time, this is probably the best. This is not easy to understand, so come down and have a try.
