Dynamite Go Go

I kind of like the inverse scrolling. This game is exaggerating everything it has, so flying in the opposite direction in an instance? I don't see a problem there.

Hehe, I don't have anything against inverting the scroll, but what I meant was that when you invert the scroll, the enemies should move up, accordingly. Otherwise, my brain keeps yelling at me that something is wrong and it's a bit dizzying haha

WHAAAAAT!!!

Thank you NYYRIKKI. It is a big shock that OTIR cannot be used with MSX1.
(Sure, the Japanese engineer's blog I referred to was for MSX2.)
MSX1 programmers are working hard on OUTI, but it's for MSX2 to speed up with MSX2 specs and OTIR.
Like the smooth scrolling of SPACE MANBOW, DYNAMITE GO! GO! Is exactly for MSX2.
Please send accurate technical explanations to users. (If it's a samurai era with MSX1 spoofing, it's HARAKIRI)

And ...
For the MSX1 version, the NYYRIKKI patch may be a global standard ... (whispering so that it doesn't sound like D4)
You guys work crazy fast.
Even if we make the MSX1 version, we expect it to have the same quality as NYYRIKKI.

Now I am studying MEGA ROM and FMPAC.
Please let me know if you have any advice that you should not trust the reproducibility of this MSX emulator.
Thank you from RUTOBO GAMEWORKS CO.,LTD.

Some users and me have talked several times of this issue in MRC forums. There is some advices that one I posted more than 5 years ago.

Several MSX1 software has been fixed by following these tips.

It fact, I/O ports number for the VDP accesses have become standard between the MSX2 and MSX2+. So we can officially use the I/O ports 98h-9Bh on MSX2+ and MSX Turbo R. MSX2s use same port except the MSX2 upgrade cartridge (which can be considered as non-standard or an mistake in the standard because of the slots management. The Bios was planned to stay in slot 0 or 0-X and not be interchangeable. Also, the management of slots and few devices are in some cases painful or even impossible if this was not the case.)

PS: Does the full version support the joystick?

BTW once more about FM-PAC...

Writing to FM-chip is relatively rare, so I think it is better to be safe than sorry... You may use official #4110 WRTOPL routine in FM-BIOS... Or you can use this version that should be slow enough to work on any MSX... Including 7MHz computers running on Z80 or R800:
