Nice! What is your top-10 list of AGD games?

I don't have a top 10. The games are varied. Some of them look great, some of the play great, most of them are very tough. It's better you find what you like, depending on your interests.

As per WoS there're only 16 AGD games (in fact there're more than 16); but the thing that amazes me is being Jonathan Cauldwell such a great game programmer, he doesn't appears in the list of AGD authors.

The WoS database has "temporary" stopped updating since 2013. Since 2013, new games are collected in the WoS Forums but not in the database, where I collect and categorise them. Detecting AGD games is hard, I usually have to ask people if they use AGD.

I can't speak for Jonathan, but his latest games are not flip screen platformers, so I think that's why he doesn't use AGD for those.

There're some other game creators ("La churrera" from The Mojon Twins came to my mind); but no one has showed too much interest to port such engines to MSX. Even the CPC has "cpctelera"...

I don't think "Interest" is the reason why Churrera wasn't ported to the MSX. The reason was very likely to be technical or perhaps a resource (money) problem.

There are dozens of AGD games which are not featured in WOS. One or two come out every month, obviously of mixed standards.

The reason I decided to post here is because there is a new version of AGD which is script based and with a front end would allow coders to develop in a PC environment, possible for multiple machines. So the AGD editor would not need to be built, only the engine to interpret the scripts.

perhaps someone can help developing a kind of code converter (to assembly, C, Boriel’s ZX-Basic Compiler, etc.) or a cross-compiler - since the idea and the need is there, i can’t see why this can be so impossible! Wink

(my laziness blocked me to understand better how the ZX-Spectrum version of arcade game designer works, i wer mostly focused on cross-compiling since years)

yes, a cross-compiler would be the way to go. I guess if someone with decent MSX coding knowledge is interested in this, just get in touch, I'll check back periodically.

Hi guys,

My name is Jonathan Cauldwell and I'm the author of Multi-Platform Arcade Game Designer, just thought I'd register to say hello.

I've just released version 0.7, it's available here

If anyone is interested in taking a look at doing a conversion for the MSX (or indeed any other machine) the source code for the engines and compilers is included. The Z80 engine source is fully annotated, every single line is commented.
Take a look at EngineTmx.asm and CompilerTmx.c, those are probably the closest to the MSX as the Timex version uses a practically identical screen mode, 256x192 pixels with a 32x192 colour attributes overlay. Sprites are monochrome 16x16.

It goes without saying that I'd be more than happy to co-operate.

Hi Jonathan, nice to see a post by you in these forums!!!

There are at least two other game engines currently being developed for the MSX from what I can read in the forums in other threads, but the AGD is immensely popular in the ZX scene, and thus, porting it to MSX would be a huge draw to bring developers to MSX! My hands are currently full with 3 game projects, but if anyone is interested in a community effort, some some shared code repository where people can start contributing to make this port, I'd be happy to collaborate Smile

Hi Jonathan,
your name is familiar to me.
I've read many times about you (and your games) in Retro Gamer magazine :)

Thanks Journey. It's always great to see a game I've written getting a good write-up in Retro Gamer or elsewhere. It's especially pleasing to be able to help others see their own games appear in print, which is the point of AGD. Smile

Version 0.7.3 was released a few days ago and can be downloaded from here. There's a simple demonstration game included, plus the latest version will import many of the 150-odd Spectrum AGD games as tape or snapshot files, generating placeholder graphics for the other supported machines. As usual, source code for the Z80 engines and compilers is included in the downloads but if you like Santiontanon's suggestion of a community effort to get an MSX conversion going I can set up a project on a shared code repository. As I said before, the Timex graphics mode is pretty much identical to the MSX so would be the ideal compiler/engine on which to base the MSX version.

We have an Enterprise version underway now and I'm liaising with the developer to get MPAGD's palette editor working properly with the machine.

I've uploaded some tutorial videos so you get an idea of how the tool works and how easy it is to create games:
