Pokémon Snap

Pokémon Snap, known in Japan as Pokémon Snapshot (ポケモンスナップ, Pokémon Sunappu) is a first-person rail shooter and simulation video game developed by HAL Laboratory with Pax Softnica and published by Nintendo for the Nintendo 64 video game console. Originally developed as an 64DD title, it was later brought to a standard N64 cartridge due to poor sales of the 64DD peripheral.

The game plays similarly to other on rails first person games: the game moves automatically as you control shooting from the protagonist's perspective. The objective of the game is to take pictures of Pokémon, using items such as apples and "pester balls" to achieve better shots. After each round, players are judged based on the quality of their photos.

Unable to Detect Pokémon
With EFB to Texture on, the game will be unable to detect Pokémon, breaking the tutorial. The tutorial level locks out the joystick and only allows you to zoom and take pictures, then continues once it confirms you took a picture of a Pokémon. But with EFB to Tex, it is unable to detect it, and enters a state where the game thinks the tutorial is still going, even after you pass it. So, it will prevent the joystick from working in game, and only the Z and A buttons will function. And once the game reaches Prof. Oak, the lack of a joystick prevents you from showing him pictures, and cannot continue past that point.

Even if you are able to pass the tutorial with EFB to Ram, save, then return with EFB to Texture, then it would still not function. With EFB to Tex the game is not able to detect what is in your photographs, and so all photos taken with it on would be considered as 0 points. Fixed by

Unable to show pictures to Prof Oak
After completing a level, the option to select pictures to show to Prof Oak is greyed out, even with EFB to Ram. It is impossible to continue through the game past this point. However, you are able to see the pictures at least...

Can't See Photos
With EFB to Texture on, you will be unable to see the photographs as you try to show them to Prof. Oak. At the moment it doesn't matter, as EFB to Texture prevents Pokémon from being detected, and you will have nothing to show him anyway.

No Sound
Pokémon Snap has no sound, with either DSP-HLE or DSP-LLE. Fixed by.
