• iBMSC 3.0 Delta (Jan 12, 2012):

  This is probably the biggest update I have ever made to iBMSC, at least up until now. Most files from previous versions of iBMSC will not be compatible with iBMSC 3.0, including all *.cff, *.th, *.lol, *.ibmsc files. You don't have to worry about most of them, but you might need to reconfigure the program as it will not be automatically imported.

  Many thanks to hitkey and Nekokan; iBMSC 3.0 will never come out without these guys.

BMS Speed Adjuster was first created only to change the BPM from 100 to 150 and to 200 for a bms named "A Minor in Presto" (快速a小调), created by Freefire, and the program was never published. However, this inspired me for creating a new bms editor since I was not satisfied with the features current bms editors could provide me, and there exists several compatibility issues between BMSE and O2Mania. After I slightly added some features to BMS Speed Adjuster, I realized that VB6 is quite ancient and has a lot of limitations, so I decided to learn VB.NET, and started writing iBMSC on January 3, 2011.
