Is the starting position supposed to be the same for both software and VLB carpet.exe?

i don't know, probably yes - you can more less tell that by looking on the map and compare both versions.
there is a spell in front of you so if you just bow down and move forward you shold hear the sound of collecting it

there is also a readme for all the tools there (mostly for 24fps patch)

Thanks!

Magic Carpet, part of the HUD near the health bar flickers and disappears. I don't know if this is normal?

check how it is in software. the 3 icons of wizard, heart and ball flicker to (i think) signal you are invincible for some time. later when you become vincible they should stop blinking.

Moving the mouse always seems to spin to the right, something's off with Dosbox-Rendition.

try using fixed amount of cycles and don't change them while in game
maybe something to do with joystick (disconnect/disable it)

I'll try that. It happens when I move the mouse.

The mouse problem turned out to be [sdl]autolock. The Dosbox taskbar icon kept getting highlighted, so I disabled it to see if it fixes things. Now the mouse works.

Joystick was already disabled and lowering cycles down to 20,000 and 30,000 lowered the framerate, but not the mouse scrolling in one direction problem.

Now for the sprite problem.

Magic Carpet with sprite rendering, the fix for the sprites kills performance:

It reuses the same part of VRAM for each sprite, overwriting it many many time each frame. I had to turn down the tracking speed on my trackball to get the controls usable, along with capping the framerate to 25 fps.

- Nascar Racing (1) This should fix not being able to enter driver info or a race without heading into a garage.
- Magic carpet should run at full speed (25 fps). Some textures may be corrupted from time to time. The slowdown was caused by my custom bitset class for detecting writes to VRAM. The granularity for this game has been reduced to 256 byte blocks, which makes the test for modified bytes within an address range 8 times as fast. This is done for every single texture every single time a polygon is rendered.

The current source including the register handling for 3DBVLB detection, and Speedy3D rendering conversion is attached. They're in a very rough state. VLBPageHandler.h has the source for the register functions for the GIGi. CGL.h and CGL.cpp contain the current 3DBPCI routines, some of which are used by VLBPageHandler. 3DBlasterVLB.cpp contains the ISA PnP and interrupt triggering code.

- Sky and sun spikes/rays don't work.
- Performance in in-cockpit view chugs a bit.

- Magic carpet texture glitching should be fixed and performance should be good.
- Flight unlimited, terrain rendering should be correct. Mouse lock prevents menu navigation with mouse.
- All previous Nascar fixes.
