NGPC Development

[Ahchay]

Hello all... It's been a while, but I've recently been reminded of my original NGPC development stuff, so thought I'd start to revisit my original code. Although I have just sold my old flash linker, so I'm in emulation only nowadays.

I have a (sometime) blog where I'm starting to put up a revised version of my old coding blog, and I have also managed to steal all of my old source code off an old computer, including a few bits which never quite made it to the outside world (a better version of Robotron for starters). Nudge me for a onedrive link if you're interested.

Anyway, the blog is active now at https://ahchayblog.wordpress.com/category/ngpc/ but I'll be dropping in here from time to time too. Am hoping, real life permitting, to revisit some old projects and maybe get one or two new things working too.

Nice!

Thanks Ed, and thanks for the promotion over on twitter

I'll be trying to do one thing a week from now on - and have been working on actually turning Robotron into a playable game - rather than the very early version that has been public for years. I hadn't quite realised how much extra I'd done on that over the released version.

Yeah, I totally get that. I assume that it's much easier to use emulation for dev/testing. Kinda like how you mentioned extra work that was never released, I know that I put a fair bit into making RACE! work on SDL (PC and Mac IIRC), but I don't know if that code ever made it to the world.

The source is at https://github.com/TheFlav/RACE-NGPC-Emulator (and https://github.com/TheFlav/RACE-NGPC-Emulator-PSP).
I GUESS I found a "released" PC version here: https://sourceforge.net/projects/koyote-...land/RACE/

I also GUESS that I forgot all about this (which you may be very interested in): http://forum.freeplaytech.com/showthread.php?tid=1764
Judge, a name that you may remember, was the original author of RACE (previously called MHE after it was called RAPE) went on to do a lot of work on Neo Geo Pocket emulation in MESS. Unfortunately MESS isn't what people think of first when they want to find an emulator for a specific ROM, but according to the thread I just linked, it may be a developer's dream emulator.

Once you're done with emulation and want to test on real hardware, hit me up in a private message or something.

By the way, did you see this other recent NGPC homebrew? http://forum.freeplaytech.com/showthread.php?tid=4551

Nice to see you back in the small NGPc world Chris.

Loïc.

Cheers both. Yeah, I saw that Bezerk clone Ed - haven't had much chance to play it yet. Too busy trying to get Robotron into a completed state, but as you say always good to see something/anything on the old NGPC.

My tutorial series is getting there - two or three more blogs to come on that - it's been very useful just in terms of dusting off all these old memories and I've been working on some games alongside the blogs.

I've been busy tidying up my various project folders. This link contains up to date versions of Barbarian Invaders, Mr Do, Juno First, SameGame, Joust and Robotron. They're all "playable" if not fully complete

I'm also in the process of uploading source code to Github if anyone wants to see the source:

https://github.com/Ahchay?tab=repositories

(I think that should work). Currently actively trying to nail down the last few bits of behaviour in Robotron and might then pick up a few other bits from there.

[Ahchay]

I have been asked to put together a quick article for http://www.retrovideogamer.co.uk/ - of course I'll be pimping my own bits and bobs but it's also a chance to put the word out about the NGPC scene.

Any recommendations for things that I might have otherwise missed?

Oh, and the "tutorial" blog sequence is finished now at http://ahchayblog.wordpress.com/category/ngpc - I'll be publishing detailed articles on some of the games over the next few weeks. Robotron, Joust and Samegame (latest versions all on the onedrive link above) - would also welcome any feedback, bugs or whatever if anyone does get a chance to play any of them.

Replace the T900 folder with this one.
