Alpha Mission for MSX - preview | MSX Resource Center

Source: Sharksym's MSX World

Recently we reported about a possible MSX remake of the SNK shoot'em-up Alpha Mission, which is currently being developed by the Korean MSX developer Sharksym. In the mean time, Sharksym has been working hard on improving the game engine, adding a BGM player, sound effects and a level editor.

A first preview version that actually can be played has now become available right here. As Alpha Mission was released in Japan under the tile Armored Scrum Object, the working title of the MSX version of the game is 'ASO'. The game needs an MSX turboR (or emulator) with at least 512k of RAM and supports both MSX-Audio and Moonsound/Dal So Ri. For those who are too lazy to run the disk image themselves, check out this video on YouTube.

Great game! The videos seem quite cool.

Bug report: I noticed a weird behaviour when tried to run it on openMSX: the game runs at half of the normal speed, and the screen flicker a lot.

That must mean his msx is broken?
(screenshots and video on his page are from msx, only one picture from an emulator)

Ok so, really... either openmsx has a *gasp* a bug, or you used wrong settings/configuration somewhere.

I think it's a bug in openMSX: https://sourceforge.net/tracker/?func=detail&aid=3427184&group_id=38274&atid=421861

The game looks really awesome. Bit of nitpicking though: maybe it's just the videos, but I don't see very well the enemy's bullets. The author still has time to avoid some kind of "Scramble Formation" effect. But anyways, the game looks great.

@Sharksym

You're not using frame interrupts at all, only line interrupts. Is there a reason for that?

1) Because the frame interrupts are still enabled and consuming CPU power
2) Because it would be easier if you used frame interrupts and line interrupts in the usual way (line-interrupts for the screensplit and frame-interrupts for vsync)

Note: I did not mean to be critic, the message was very short and direct because I wrote it from my cell phone.

just a curiosity
from the video, tecnically speaking ASO uses only msx2 features. non V9958 specifics are here.
Can you tell us why a TurboR game? do you need computational power ?

Perhaps this is a good sample of 'creating the game for turboR is relatively easy' as opposed to 'creating the game for MSX2 would require some serious optimization skills'. Also, the use of Moonsound for music and (stereo?) sound effects might be a bit more CPU intensive? Either way, the remake looks good and it's nice to finally see some turboR software again.
