In emulation yes, not on a real B with any of my LCD screens. Something is off in the 6845 timing, I just get a rolling screen.
Never heard that before. I've played it on real hardware plenty of times in recent years. Well, once it's open-sourced, you can fix it :D

Re: Starquake revisited: we need your help!

One of the few games I own from BITD. Sadly none of my LCD displays will sync to the game, I just get a scrambled mess... perhaps that can be fixed. That's curious. Presumably the online version works? http://bbcmicro.co.uk/game.php?id=556 [edit: link fixed, thanks lurkio!] Are there plans to add t...

Re: Starquake revisited: we need your help!

My main memory of the Starquake code is the protection system! Getting it from tape to disk was a two stage process: stage 1 involved decrypting the loader by duplicating and executing lots of tiny little loops by hand which decrypted the next few bytes. This process took a few days! Matt Godbolt a...

Starquake revisited: we need your help!

Receiving Acorn: A World In Pixels has been a somewhat emotional experience for me. I love how Mark has expressed my thoughts in the published interview, and it's reminded me what a fantastic time of my teenage years this was. And with several decades of programming experience since, I'm sure it cou...

8e is never updated, so move the sta &8e after the lda #0 at the top of cls_l1? 2 bytes saved! Slower, though. Yes, easy two bytes there! Speed shouldn't matter, it's called once every 256 times.

Heads-up that I've got a new laptop with Android Studio running for the first time in five years, and I've got the rocks-and-gems Mole Miner compiled, rudimentarily changed and republished to Play Store so you can at least play it on modern hardware compliant with modern Play Store policies.

Reuben's intent is to make the web app so good that you don't need a native app. Having said that, the native app could be replaced with a smart wrapper to the web app, to save you clicking the URL, and to remove the browser chrome.

Hey, author here. I don't remember how this was done now, but Arcadian has all my source code disks so might be able to assist? The tape and disk protection were done later by (different) others, so the protection won't be on those disks. There's certainly no hidden levels on the disk version, sorry...

Re: Game requests to be added to Beebdroid for Android

It can basically load anything from STH, but the list of available games is hardcoded on STH. It's about 30 at the moment. Then the emulator needs to map keys. We're hoping to improve this process soon.

I've (*) just added Football Manager and Twin Kingdom Valley, they didn't require an update to the app. Any others, shout :-)

(*) or rather, Dave Moore helpfully uploaded the updated available files list to stairwaytohell so the app can see it.

Hi y'all. Having a bit of downtime, I'm going through the email requests for games to be added to Beebdroid for Android. The master list of games is incidentally hosted here on STH. If there's anything you want, please provide the link to the disk image and the cover art, cheers!
