A flashing K or an inverted K?

An inverted K is the cursor for the ZX81.

Therefore, the next challenge is to convert the two WRX files in the following link to QS HRG, that Greg reported earlier, he was able to do. LABEL__64K___16K DFILE_9613->16627 WRX_HIRES_9640->1665...

Re: VB81 Hi-Res Hiccup

VB81 Developer, etc., You can use external libraries or API calls to achieve more accurate timing functionality in VB6. For example, you can use the Windows API to call assembly code written in a separate DLL file. Here's a simple demonstration using inline assembly in a DLL and calling it from VB6:...
