Within the first 2 weeks of it's release, this emu got a ton of updates and progress from Zod. The same can be said currently of SteveM's Mame emu, and others as well.
Once these guys get to a certain point, much more time is needed to further progress. During the GP2X days, I would sometimes see so many updates that I didn't have time to try them all, and then you could go weeks(months) with no updates at all, that's the nature of the community. There are many PS1 games that run full speed at default settings, and many more that run very well with some overclocking.
Right now, PS1, N64, and Mame need a lot more work to get to that next level of improvement(Mame is awesome now, but needs to run later games). These things take time, and the current guys doing all this work have day jobs, families, school, ect. They may have other things in life that have higher priority than hacking away at something that is a hobby. I'm sure there are many more guys out there who will help out, and pick up the torch from the current group, but with only 1000 units out there, this will be slow to happen. Hell, Pepone is doing Neogeo, and he can't even test his code out, as he doesn't have an actual Pandora.
Come on guys, improvements will come over time, and when more users actually receive their units, this community will thrive. Just sit tight, and enjoy what is currently available, and keep testing and giving opinions on the current lineup.
For those who have enjoyed what is currently out there, please give a donation to the developer. Don't wait until perfection happens, let these guys know their hard work is appreciated now, and not later.
