Subject: [stella] VDELPx From: Thomas Jentzsch <tjentzsch@xxxxxx> Date: Tue, 14 Jan 2003 23:42:17 +0100 |
One question about VDELPx. How exactly does it work? I found two possibilities: 1. VDELPx changes the GRPx-register where the value is written to 2. VDELPx changes the GRPx-register which is displayed Example: If I enable VDELP0 and write value A into GRP0, then disable VDELP0, and write value B into GRP0 and then enable VDELP0 again, what is displayed by GRP0 now? 1. B (because it was written into the visible register) 2. neither A nor B (because nothing was copied into the 2nd register, which is now visible because VDELP0 is enabled) Can I trust z26 (2.) here? Have fun!
