Work in ProgressThis is a design document specifying the functionality of a program that is not finished. I've implemented a lot of the functionality described below, but not all of it, and there are probably a lot of bugs. I can make an alpha version ava …

Question about .chd files: Now that chdman is able to compress chd using zstd algorithm (which is in every way superior to other algorithms), does anyone know if there are plans to update the MiSTer to be able to read zstd compressed chd files? …

hi, can anyone define an interface for a Z80 coprocessor, implementing at least integer multiply and divide, and better also the IEEE 754 standard for floating point operations?Add those instructions to the Z80 base set should enhance the performance enou …

I've been using a pair of LXP-5's for the past 35 years to elevate my vertical mix. The pitch delay algorithm has an ambient Reverb that can be detuned to help with this. I bought this particular LXP-5 along with another 20 years ago. This one had …

I've finished a new version of video converter for C64 and Super CPU. Added a 4bit 4.4 kHz digitized sound and a new algorithm that redefines character set for each movie separetly. The new character set is not visible in the preview mode.Application is w …

I was briefly tempted to necro this thread as it is the top google hit for "8088 prefetch algorithm", but I will be good and post a new thread instead. I believe I have figured out a somewhat simple logic behind the 8088 prefetch algorithm, and …

I'm the founder of Blur Busters and creator of TestUFO, and want to make an announcement of one open source code module (used in TestUFO and VSYNCtester) that will be useful for some emulator authors.I happen to have experimented with the world's first cr …

(I'm the founder of Blur Busters and TestUFO. I was making a reply to author of MartyPC emulator, but realized this was worth its very own thread topic)PURPOSE OF POST: Since there isn't an ultra-lowlag DOS emulator yet, this HOWTO is for PC/DOS emulator …

Hope this is not too far off-topic, but my retro adventures have led me down this rabbit hole now..In his thought-provoking 2006 article "Why Johnny can't code" David Brin discusses the value of a universal (yes I know), readily available (at least in the …

Please restore format 0.1 from DOSBOX version 0.72. The new algorithm has many bugs:1) The DRO 2.0 format doesn't save A6, A7, A8 and B6, B7 and B8 registers if the file contains writing of BD register. The file contains malformed information about percus …
