Lo cierto es que yo aún no lo he probado. No quiero perder el tiempo en algo que vaya lento.
Sin embargo han sacado un faq. LEED!

**************************************************
Q: How to improve the speed?
A: As you know, Symbian is a very complicated system. Everybody's mobile should have difference to make vSun faster or slower. The background application will cause vSun slow. The "disk" free space also affect the speed. To make vSun faster, uninstall unneccesary programs and restart phone to free enough memory.
Q: How much memory vSun use?
A: It is less than 2.1M plus ROM SIZE. The SuperFX is supported and it needs another 4M memory. The additional memory is allocated to RAM,SRAM,VRAM,Tiles,APURam,Screen Buffer,etc. If your memory don't have enough memory, try use smaller rom.
Q: What is the meaning of sound option "Off","Smart","Full"?
A: It is the emulation way for optimizaion. "Off" means just skip APU emulation and cheat CPU. "Smart" means APU emulation will be within a small time. "Full" means full emulation of every CPU,APU cycle. "Off","Smart" both have problems with some roms. "Full" is slowest and have good compatibility.
Q: Does trial version has sound? Should I need register to have sound?
A: Trial version has sound. After switching, you should reset game. Different emulation way also cannot share save/load states.
Q: Why not add effects option? That will speed up!
A: After hugh tests, the main bottleneck is CPU emulation. Graphics is not the true problems.
Q: What about frameskip?
A: The concept is that you cannot skip the CPU frame. What you can skip is graphics frame. The graphics frameskip is 4 in vSun. It is appropriate. To increase or decrease will not get better speed or better feeling.
Q: Why picadrive is good and vSun is slow? MD's CPU frequency is higher!
A: We cannot judge the emulation difficulty simply by CPU frequency. There is also APU chip,GFX chip,etc. The way to check "dead loops" is also the key difference. The compatiblity also counts.
Q: Is vSun fully optimized? What about ASM?
A: vSun is programmed partially in inline assembly. We even examine the compiler result sentence by sentence to get best result. The graphics filter part is also programmed in ASM.
Q: It is really slow on my phone, I want to complain here!
A: Sorry, it is not slow on every phone. If you are interested in vSun, try and enjoy it. If you are satisfied, purchase and support us. If you feel wasting your time, I must say sorry, but please don't complain here. Even before the final release, we have posted the exact speed here. However, many users have responded to us that they feel speed comfortable and have purchased our vSun. Thanks for registered users!
We will continue optimizing vSun and release upgrades. Maybe next version you will get surprise.

Dicen que puede que en la próxima versión nos quedemos sorprendidos
¿Puede ser que se esten guardando una version mejor para ir actualizandolo paso a paso?
Si consiguen una versión decente para mi gusto estoy dispuesto a comprarlo aunque cueste 20 dolares
