When you follow games for so long you should get accustomed to push backs on release dates. 99% of all the MMORPGs I have ever followed had been pushed back more than once, and that is with hundreds of people working on the game and tens of millions of dollars. This is being developed by two people on spare time. I saw Mr. Y updated SNESoid today. Looks like PSX4Android isn't his only priority.
Give it time and the emulator will be here when it gets here. If you have questions feel free to contact the developer. You are potential customers and he should be more than happy to assist you. This is his business.
NCAA Football just came out, play that for a bit or play an old school game on an emulator on your computer. Or just keep trolling the forum ;-)
