I later looked for a sound test and it was Just hold A and press start. Welp. I really should start finding these simple cheats again. Valid song ID: 65 68 6B etc to 8C. This is one of Alberto Jose Gonzales' amazing works on the Game Boy.

Super Mario Bros.

Improve Power Glove Control
ZASLPKIO

Last night I had the idea to make games more compatible with the NES Power Glove, for better or for worse. I was binge watching Gaming Historian videos (I rarely do this in general these days) and I was upset that Novac's games weren't released as Power glove exclusive titles. I soon raised the same point on Twitter soon after with the idea to make games work better using the device. Super Mario Bros. is the first test subject and it works. Well, at least without completely rewriting the physics engine (I could do it but it wouldn't work on hardware without a flashcart, and who has the time?) So, I came up with a solution to make Mario controllable anywhere using the A button, or if you're using the Power Glove, make a fist and release to drop Mario. Mario's Y position is controlled by the Power Glove's internal setting for each game it is supposedly supporting backwards-compatible control.

Here are the original twitter posts:

The latter:

Conclusion: The proof-of-concept works but there is a potentially problematic limitation as a direct result of conflicting with the climbing physics routine you will become stuck when entering a new screen from a vine climbing upwards. Using two byte changes, this is a really a remarkable fleet considering I did it in 8:12 minutes. Unfortunately I do not have an NES Power Glove to do further testing and codes. This is all based on limited experience with how the Power Glove operates and understanding how it interfaces and reacts to physics. A later revision may be a workaround for fixing the climbing issues as well as making Mario's speed controllable.
