I cooked a ROM in the
ROM Kitchen yesterday, have used it on 3 different SGS so far and I have to say it's fast as lightning on all of them. Faster than Darky's 9.5! JS8 base, JPY modem (GPS is fast to lock), speedmod k13d 500Hz kernel (no tweaks or lagfix on). No bugs at all so far, dead stable. The only drawback is the choice of themes don't have any good previews. I used the Docrom v4 theme but I did prefer the Darky's style.
Only oddity I noticed was that from the stock JPY kernel to speedmod (and voodoo), the screen looks very blue. Any reason why? I think speedmod has an option to alter that, suprised it's so different from one kernel to another. I compared JPY, speedmod and voodoo all side by side and only the first had realistic colours, the other too have too much contrast and blue! Any tips?
