If you have any doubt about a game running on your mobile. Check for problems/compliance issues with any of the following facts about your E-75.
Developer Platform:
S60 3rd Edition, Feature Pack 2
Operating System:
Symbian OS v9.3
Screen Resolution:
240 x 320
A game made for other platforms or operating systems will probably work fine (Java is not tied to the host OS for compatibility). However a game designed for a higher resolution will most probably fail to load.
