New video: Let's Code MS DOS: 0x37 Rainbow Surf Analysis
This year's Revision demoparty had a surprising winner in the 256 byte compo. It was Rainbow Surf by Plex/BionFX and it is only 16 bytes long. That is short, very short. In fact, here is the code: c4 04 48 ab 26 03 45 ae 26 03 05 c1 e8 02 eb f2. Let's dissect it!

The Yamaha #opl2 is documented to have an ADSR curve where the key off triggers the release phase, as shown in the picture. However my tests using DOSBox show that the key off doesn't matter at all. It seems release is triggered as soon as decay phase is done. Is there a trick or another register that controls this behavior?

New video: Let's Code MS DOS 0x26: AdLib Drum Machine
Programming the OPL2 FM chip on the original AdLib card can be a bit tedious. Join me in this episode to learn how to program the drums on the AdLib card to create a simple sequencer or drum machine. In the future we will also look at the melodic instruments, but for now we try to create some nice percussion!
