hey guys. Portsing SYS is very easy, especially with my rollup sorter.. get it here.

basically you just take the ROLLUP folder from da_g (wm6550_whatever) and drag in on to my batch file. enter the hres (480) vres (640) dpi (192) and lang (0409 for english, others for others) then it just goes. at this point you will still need to remove some more stuff
first, copy your last build's ROM folder side by side with the last, for example if that is 23518, create a copy of 23518 and call it 23541 (or whatever your new build is) in there, delete msxipkernel, replace it with the one from your newly created SYS folder) then just copy your new sys files into a new folder in SYS with your buid number as the name. delete anything that has _CS on the end, also if you come upon MediaOSfiles and mediaOSmodules, remove the modules one and keep the files one. This will occur a few times , baseappsmodules, mediaosmodules, and some others. remove and commonEA, bronzeEA, lockscreenEA, nonphone, gb18030, irda.. I think that is all, if you have problems post here and I will try to help. sorry for the big jumble of unorganized information, its early in the morning!
for sys that is already in VK format the kitchen does the work for you...
