In 1993, I was a third-year high school student and used the MSX2 to create a 3D game written entirely in machine language.
I had intended to use the LINE command of the MSX2 VDP to perform ultra-fast 3D calculations and display the game in machine language, but I felt the speed limit of screen clearing and LINE commands, and I gave up on adding bullet shooting because it would have significantly increased the number of collision detection processes. (It's a game where you just dodge, and you can only attack the boss by body ramming.)
I also hadn't implemented sound processing.
I had originally planned to have about 8 stages, but I got bored after implementing 4 stages and gave up. Anyway, implementing enemy objects was difficult, and I was running out of ideas for stages.

To slow down the speed, the score drawn in LINE was only displayed when the button was pressed. I divided the stage into a first half and a second half, and in the second half, the horizon was erased. (The screen getting darker unexpectedly gave the feeling that I was on the way to the boss, so this was probably a good thing.)
It was the limit of my ability as a high school student.

In 1996, I was hoping to get a job at a game company, so I added a stage selection screen, created a practice mode that could be played on only one stage, and made it possible to automatically start from MSX-DOS in order to submit work to a company called Con○○il (such as Pu○○pu○○).

However, from my year, Con○○il stopped accepting work on MSX, so it ended up being a waste ＿|￣|○
※I submitted a different work to another company and got a job offer.

The only use for it was releasing it as a mega demo on Youtube.

I captured the video almost 20 years ago, and since the machine at the time was slow,
there were frame drops during capture, so it's a little faster than the actual speed. (The volcano stage temporarily went up to about 30 FPS.)
I think the actual speed was about 4-6 FPS.

It was heavily influenced by the Game Boy X.
Return of Jerda and Silpheed are amazing. Star Fox and Red Alarm on the Virtual Boy, which came out later, are the coolest.

*The name that appears in the ending was changed to a fake name using a binary editor.

*When the video was released, it was also featured on overseas MSX forums.

*The final version was lost, but in 2010, the source code and software of an intermediate version were released.
