<div class="markdown_content"><p>Where C-BIOS v0.17 worked (almost) fine with RuMSX, <br /> C-BIOS v0.20 has several problems:</p> <p>1) boot-logo is corrupted, at least after a reboot of the <br /> MSX. This problem has been solved in C-BIOS v0.20a.</p> <p>2) the boot-logo is only displayed partially (was correct <br /> until C-BIOS v0.19). I could not find the cause of this <br /> problem right now.</p> <p>3) Pressing the SHIFT key should activate the <br /> debug_mode. Pressing SHIFT in v0.20 displays a <br /> corrupted text-screen. V0.17 was almost fine, some <br /> newer version garbled the text screen. Looking for the <br /> cause I've found that the routine 'init_vdp' sets the VDP-<br /> register 2 to the value 0 (PatternNameTable=$0000, but <br /> should be on $1800). I guess VDP-register 2 should <br /> have the value 6 instead...</p> <p>4) Working around the problem (3) or using C-BIOS <br /> V0.17 activates the debug-mode but does not have a <br /> proper line-break. See 'cbios_debug.gif' for more <br /> information.</p></div>
