the V4 seems to be running smooth. even with my slower computer, its generating lots of hashrate. its taking a goodly while to solve a block, but im guessing there arent too many on the testnet right now. ive got both CPU and GPU miners working on it right now and will leave it running overnight to see how things go. but its running nice right now, faster, id daresay, than the ETH or EXP networks have run for me....

im a fan of the ETH forks, found that the integrated ethminer works great for me, while ive had nothing but stress working with other mining programs. in the OP you had mentioned a .bat file ("gpu_mining_solo.bat") for GPU mining, but that didnt come included in the package. i checked the wallet_V2 package and the soil_win_x64_v3 package. will the GPU mining be done with ethminer? if so, you could do like the EXP package that was released and include that in the windows download. i attempted to add, as they did, ethminer.exe and libcurl.dll to the wallet folder, but you still need that .bat file for the GPU mining, for example, from the expanse coin package, their start_mining.bat with ethminer looks like this:

@echo off
color 0A
"ethminer.exe" -G -F http://127.0.0.1:9656

im presently working on packages (albeit, slowly) with gsoil, but although ive committed work on block 16720, its been sitting there for about ten minutes. is there any way you can get the gpu mining thru ethminer working with the package? would make things much smoother.  also, why the lack of GUI wallet and other stuffs from teh V2 package to the bare bones V3 win64 package? all in all, seems great but needs some tweaking. could you post your gpu_mining_solo.bat here?

regards.
