Okay, I checked out this hack to see if everything was true to the original “Super Mario All-Stars”, as well as the classic versions. Most of them are faithful to both. However, I noticed a few differences.

For “Super Mario Bros.” and “Super Mario Bros.: The Lost Levels”, Lakitu throws Spinies at random places, like he does in “Super Mario Bros. 3″. Perhaps it is a coding issue. Not a huge deal, but definitely not for speedrunners because of that. Also, at the end of World 1-2 in “Super Mario Bros.”, when going for the wall clip glitch and taking the first warp pipe, it just goes to the minus world, not from the Famicom Disk System. That would have been nice to add from the Famicom Disk System. Perhaps it is not possible to implement.

For “Super Mario Bros. 2″, everything is faithful to the original. However, I have heard that there are problems of this game working correctly on actual hardware, particularly the CRT version, where the player is sometimes unable to proceed past World 1-3 due to it looping, as well as the saving problem at certain levels, such as World 6-1. This needs to be fixed if that is the case.

For “Super Mario Bros. 3″, everything is faithful to the original. However, I do wish the text for the match game and the ending showing the names of every world was from the original “Super Mario All-Stars”. That one uses the PRG0 version. Possibly the most infamous quote typo ‘Miss twice and your out!’ is what I am used to. As for the world names, I find the PRG0 version more interesting than the PRG1 version. Perhaps another revision can be made on that so people can choose what they prefer.

For the arcade “Mario Bros.”, controls are improved, and the high score saves. Much more enjoyable overall.

Now for the file save system… Saving works as expected. However, when finishing any of the “Mario” games, there is no true world/level select. It does not work exactly like the original “Super Mario All-Stars”, where finishing a “Mario” game grants a world/level select. Even in “Super Mario Bros.: The Lost Levels”, when the player finishes that game as either Mario or Luigi and the player saves afterwards, he/she is stuck playing as either Mario or Luigi on that save file. Perhaps in the future, that can change.

Oh, and one more thing. In the “All-Stars” version of “Super Mario Bros.” and “Super Mario Bros.: The Lost Levels”, high score could be erased by doing a certain button combination. But in this version, that is not really possible on a file that is saved. Perhaps that can be implemented in the future.

Overall, very good hack…except for “Super Mario Bros. 2″, regarding the problems on actual hardware. Here is hoping for more improvements in the future.
