Been playing this hack today. It's got potential, though the major sound corruption and grammar issues are a nuisance.
The only thing that really pissed me off was being one-shotted by an Abra because Axew's secondary type is set to fighting. Axew is supposed to be a pure Dragon-type.
On another note, some of the cries seem pretty off. Mienfoo has Rhydon, Shinx is a low growl, etc. There's some issues with sprite centering on the Pokemon, as well, and a lot of the trainer sprites could use a brush up - they tend to be lacking in the shading department.
