That sounds great , so what exactly is an extended adf? Does the Amiga see it as an actual hd ? In that case save games might be possible in some way

Great game works really nice Using SQ and not dma on this

Emulated Paula has never sounded so good Ian - they really are some chunky level sound effects!!

this bring back memories

one of the first originals i got back in the day, i still have it; great arcade feeling
the bad part of the short story, is that in the same day i bought also the crappy Vigilante

so a 1.9mb adf like a mini hardrive

watch out for the extended .adf Ian
iirc they seems to work fine, but the loading will stuck when searching something that oversize 880kb

it's like you can play the game until his half
i remember some tests i made back in the day
ie Turrican2 extended .adf can be tested in the main menu, pressing 'spacebar' you can access to the music menu, and when trying to load all the later levels musics, the game will stuck

of course, i dunno if was some issue just on the .adf's i have tested, and of course it would be great if you have improved/unlocked them

no idea, i'm distant from real hardware atm, i cannot check
theorically, it should lol
can you test it on your side?
here, the test .cdi, built with the Ian v3 release :

MoonStone_AB.zip

It did not work I'm afraid. Seems all disks was detected but stops loading after 10 sec on this screen:

ouch, but thank you for the test
mmh, i think the problem is that the third disk (where the boot file now is) is recognized a bit too late, so the startup-sequence fail to load
adding a wait time delay should fix this, i presume
i'll update this

I will test it and see seems to be all good on this adf plays a lot better then the normal turrcain it's my day off day get back to it tomorrow working on speeding up the blit speed right now

Just so you know silkworm is using SQ to DMA users have reported it's smoother with scrolling left and right.. not final blitter update it is faster but pretty sure i can get this a lot lot better..

Want see when i get this done the type of speed it will bring here is my SDL dreamhal with TapamN SQ

Talking double speed for both the above higher the number better here..

I need to port my own blitter routine to the above it's taking time then we see a major speed up

New SQ to DMA

This will speed up all my older projects 320x240 HW blit is double the speed of the old way of doing it
