Originally planned as an ZX-Spectrum game (also in development), the well known Retroworks team decided to port this promissing platformer & action game to MSX2 as a result of a wise proposal, wise decision!

The game requirements are MSX2 or higher and PSG sound. It is worth mentioning that this is more than a simple port, the graphics have been improved a lot with colorful characters and scenarios, an aditional tile layer has been added in order to implement interesting in-game effects and the map needed to be modified in some areas.

If you want to enjoy this jewel, please be patient. It is expected to release the game by the end of the year, until then, nothing better than a video to experience the final result.

Retroworks developed amazing ports and games, which I just recently noticed. I´m curious about IANNA and hope they will also release new batches of their cartridges.

Awesome stuff. Very nice looking graphics and animation.

Btw funny: When I first saw some camera footage of this game (recorded during a fair) a few weeks ago, I thought it was called Sword of Lanna Big smile

oh,wow. That looks seriously good. The main sprite is awesome, the detailed animation rocks. Technical it seems like a high-end game. Hope the play ability is just as good as it looks.

Screen 5 or 8 ?!

Sc5, when I tested it in retromadrid I asked the mode and they confirmed me SC5, the truth is that the coloring of the spectrum version has not broken the coherence of the set.

That one doesn't seen the screen 8 palette. It has to be screen 5.

My only fear is that the end result won't be compatible with NTSC televisions. I've only encountered two games so far that have no compatibility for NTSC TVs whatsoever (Manbow 2, and Crafton & Xunk), but just the fact that one of them is a high-profile homebrew game that I think also used screen 5 (unless I'm mistaken?) gives me the slightest tinge of concern.

If anyone from Retroworks is reading this, and can confirm that allowances will be made for NTSC in the final product, it would definitely put my mind at rest.

There is no reason for this kind of games to be restricted to PAL, do not worry, it will work fine at 60hz

In 50 Hz mode there is much more time available per frame: 20 ms time instead of 16.7 ms (20% more). Additionally, because the VDP is idle a larger portion of the time, VDP commands can process more pixels, going beyond the 20% the extra time alone accounts for: 27% more pixels when sprites are enabled (~6% faster), 21% when disabled.

That 3.3 ms extra time is a significant amount, and affects all games, MSX1 and MSX2 alike. The VDP command speed only affects MSX2 screen modes, so in that sense there is a slight additional benefit to 50 Hz there, but I don’t think the difference is significant enough.

So rather than this being about titles using screen 5 or not, I think it is more a matter of, titles which are pushing the system to its limits (=high-profile) are more likely to make such a choice, because they simply do not run at 60 Hz without making significant sacrifices. E.g. Uridium is also an example of such a title, luckily it was built with 60 Hz in mind from the start, but for Uridium 2 ARTRAG is basically facing the same dilemma.

I don’t think it’s an excuse, software should IMO always be built to support 60 Hz. That said, I can understand making the choice because 20% extra time is a significant amount, and can make something possible that otherwise would not. And since we use RGB connections in Europe which work at both 50 Hz and 60 Hz, a case for users to "fix their cable / equipment" can be made. (I understand in other parts of the world this isn’t such an acceptable trade-off.)

But personally I would rather try to adjust / omit some game feature (e.g. lower speed animations or sprite updates) to allow the game to run at 60 Hz. My software will be certainly be built with 60 Hz as a basis. Not only because it is the minimum spec, but also I’ve personally always liked the 60 Hz frequency more, especially on CRT monitors the refresh rate looks nicer, smoother, and the image is taller and has nice scanlines.

Then again, never *force* or default to 60Hz on a 50Hz machine. Original '80s tv sets that were used with MSX computers were often not compatible to handle 60Hz, making a few games such as Boulderdash (which buggily switches to 60Hz on MSX2) unplayable for me back in the days. So the incompatibility is a two-way street.
