Extended Basic ROM

My friend Stuart (of pcBBC fame) wrote this in his youth. This weekend we managed to rip it off of the original disks and with the interest in BASIC V elsewhere here thought someone might be interested. It is an extension ROM (that must be loaded into SWRAM) that added most of the BASIC V style synt...

Re: May 12th-14th 2017 Cambridge ABUG (FULL) & Acorn World event at CCfCH

Hi All - I'm hoping to visit the museum with the family on the Saturday during the day and swing by to put names to faces. Any chance of seeing Castle Defender on real hardware? - It would make my wife giggle. :D

Re: New Release: Castle Defender

Hi - Been having a brief char with Lurkio and unfortunately the way the code's constructed it's not going to work off of a tape image. Given the amount of data that I load for levels even SWRam is not really an option (it would need around 80K...) Just as a note - I am beta testing a new release wit...

Re: New Release: Castle Defender

Thanks for all your comments. I am putting together an update which incorporates some of the suggestions being made above. For anyone struggling if you press the number keys 2,3 or 4 at the "press any key to start" prompt then the game will start on that level - although it won't record a ...

Re: New Release: Castle Defender

Hi Tom - Thanks for taking the time to comment - and play the game! AFAICT, up and down move only between slots with the same X position (with wraparound), whereas left and right cycle through all the slots, by X position first then by Y position. Yes - it does work that way. It was a limitation on ...

Re: New Release: Castle Defender

Glad people are enjoying this. The direct link isn't a problem but you may need to update it if there's a version 2. If there is shield present on the nasties the amount of shield is subtracted from the damage done. So unless you have a tower with a very high damage then you're unlikely to damage th...

Re: Tower Defence Game - Part II

Update time - After some playtesting I discovered it was possible to "spam" a level with a single or few high level towers. Consequently I've re-jigged the costs considerably. As a side to this I've ended up basically doubling all the gold values since larger number are always better :wink...

Re: Tower Defence Game - Part II

Ok - Recorded using a screen recorder so not the best quality but here's the first two waves played with deliberate mistakes :D

Balance is still being tweaked but I would expect that the first level (five waves) should be reasonably easy to beat.

Re: Tower Defence Game - Part II

Just a quick note. Still working through levels (always knew this would be time consuming). I am about half way through level 3 (of 4). It's hard to judge the difficulty level - am I just rubbish - or is this level actually impossible ;)

Re: Tower Defence Game - Part II

It's not a platform that I was ever familiar with BITD - if someone can give me a list of things I'll need to change I might be able to have a look when it's done. However I'd rather concentrate on getting a Beeb version out first. From things I recall seeing I've got a custom screen mode (256x256)-...
