Yep. @MSXARM. It's a project in progress. The MSX original Z80/R800 is replaced by an ARM Cortex M7 processor and the Z80/R800 processor is emulated on ARM(ARM assembly) 100%(not 99,99%) cycle accurate with the MSX internal Z80(not R800). Only the Z80/R800 is emulated. It's a hybrid technology! It's almost the same technique used on Apple Macintosh transition from Power PC to Intel processors(https://en.wikipedia.org/wiki/Mac_68k_emulator).

this is a R800 emulator on steroids for MSX. Not a new MSX.

Release it on a new encasing, using a new keyboard (not an Expert/Philips/Sony one) and then we'll have MSX3 to talk about. Until then, is just an (incomplete) Turbo-R upgrade kit with some cool and useless features. (and try replicating S1990 then we'll be talking about an complete Turbo-R)

You have to be a professional software/hardware designer to know how hard is to produce a complete Turbo-R upgrade kit or a complete MSX 3. It's a lot of work of software and hardware. I think it's an utopia to make such a device,unless you have one milion dollar budget!!!!!! But you can dream the impossible dream!!! It's free ahhhhahaha

I think the useless feature that you mentioned on @MSXARM is the new MSX LUA(http://www.lua.org/docs.html) interpreter. You can think it's useless but on a software developer point of view it's very usefull(and cool) feature! And it's a feature very achieveable (not utopia). It's very achieveable because the source code from LUA interpreter is opensource,is ready to use, it's high quality software. I spent just some hours to integrate the LUA interpreter and the MSX. I spent just some more hours to create some MSX compatible funcions on LUA: poke,vpoke,play... . This is very achievable . An utopia would be, to write a new MSX Basic interpreter on ARM 32 bits, compatible with the original MSX Basic.Hundreds of hours of hard work. Just utopia!! Just to dream!!

I spent hundred of hours coding the Z80/R800 emulator. 10,000 lines of ARM thumb2 assembly code. It's passing all ZEXALL tests and I successfully downgraded MSX TurboR to MSX 2+ running in this system(For now on openmsx). I working on upgrading 2+ -> TR.
An utopia would be to try reengineering the S1990(Turbo R) chip. Just utopia. Just to dream. In the real world what I'm building is what is achievable.

The @MSXARM isn't an emulator. Only the Z80/R800 is emulated, so it's a hybrid technology. Emulator is openmsx, bluemsx, etc.... But I think it needs a master degree in computer science to know the difference, or maybe to work hard trying to build such device :P

I don't need to be a professional software/hardware designer to know that doing anything that could be called MSX3 is far more expensive and demands far more work that a single person (like YOU!) can put togheter. So, the only daydreamer here is you.

And about LUA scripting... MSX coders don't even code for things that already exists, like V9958, R800 (both of these have exclusive features that no one uses) and V9990, What makes you think that someone could possibly adopt a such thing? Only because YOU think it's cool? Really? Are you that badass human being? How come I never heard about you outside MSX scene? Oh, I never heard of anything you do but this MSXARM, and the last time you posted something was almost 2 years ago! (I really thought you gave up doing it a long time ago) Less ambitious projects from more capable people (like Oazem's VSU) never made it, what makes you think you'll can do it anyway?

Anyway: Have you ever asked how many people would code for this kit of yours? It's a simple question!

WOW! you really read what people are telling! After being ignored a few times on past, I'm moved!

(rant alert for anyone that isn't @rogermm: I would sent him this privately but I think people should know better this "fellow" brazilian. If you think you would feel offended, my apologies and please don't continue your reading. Also, sorry my poor and dirty english, I can't help writting correctly and politely right now.)

Yet: I have strong reasons to belive that you don't know a F@#K of what you're doing. That's great, we all learn a lot of things during developement, no hard feelings at all. But once I made you a very elaborated question about one of the MSXARM features and you simply answered me "is too complicated for you to understand".

So, (let me be crystal clear here) It's personal. And you made it personal that day.

From that day I learned two things about you: You are not even half the capable person you want the world to believe, and you are an AS#@$%@E. And from that day I never read nor mentioned anything written or done by you. Until today, when you decided to act like an attention whore over my answer to someone that weren't you in the first place, calling our attention out for some vapourware that didn't had any update in the last two years. (yeah, I had to check to write this)

So, don't "f-word" me, and leave my mother out of this, you crybaby (do I need to be careful with spitting?). I'm taking extra care now to not answer anything you posted, so please be a man and do the same.
