Well, thanks anyway... At least I know where to look for the problem.
And thanks for your enhancement patches!

I'm having a "minor" screen corruption problem with Laydock2...
Machine is a VG-8235 expanded to 2+ according to the info posted here.
Basically at the selection screen, where you have to select newgame/continue/joystick/keyboard, the screen is split in 4 parts: Top left shows multiple copies of the the choice , rest of the quadrants shows garbage (parts of the background).
The game is playable, the intro is perfect and when in game mode there aren't problems.
Could it be that the ROM with the logo/FM pac is the problem? Does somebody else with an upgraded 2+ have problems?

I tested the roms from that topic in openmsx (as my 8245 still has an older version of the roms with kanji rom instead of the logo/fmpac combo) and Laydock 2 seems to work fine.

Perhaps you can try to dump the roms from your 8235 and compare them to the roms from that topic to check if they did not get corrupted somehow?

I've tested the ROM sets in openmsx: I confirm that the set you posted works fine (and although I don't use it anymore in my machine, I've never noticed anything wrong with it), while the one I built has the problem. So it's my fault, sorry.

But I can't find where's the trouble with my mods, I've built a clean ROM set from the untouched newbios source and I still have problems.
Either I'm doing something wrong with the config or the the source package I've been using is damaged...
Is it possible to find a new version of the newbios package or do I have to use msxsyssrc?

And here goes one more announcement:

Ghost is a fantastic a-la-Maze of Galious style game developed by unepic_fran where you control Ghost, one of Viktor's agents, who has the mission to destroy a computer that went mad and is now controlling the Dallas space station.

This patch makes many improvements to the game:

  • Fixed the PSG replayer, so now the whole game passes the Acid2Test
  • Fixed a bug where the password could not be typed if the caps lock was on. This was a problem with the Sharp Hotbit computers, since they have the capslock enabled by default in their BIOS. The first impression was that the password screen just didn't work on the Hotbits.
  • Implemented a new interrupt handler, for many reasons:
    • It improves the game performance and reduces the tearing that happened in some more crowded areas
    • It also allowed the keyboard buffer flushing routines to be eliminated from the game, saving more CPU time.
    • This also fixed the problem that the keyboard routines had with turbo, probably leading you to disable the turbo on turboR machines
  • Implemented full joystick support. This way the game can be played entirely on the joystick, without having to get out of the comfort of your sofa to reach for the keyboard ;). The new controls are:
    • Joystick Button-2: pause the game
    • Up in the pause menu acts like RETURN: teleports you to the center room
    • Down in the pause menu acts like CTRL: teleports you to the area-4
  • Since there are no more problems with turbos, now the game enables the turbo on any machine that has the CHGCPU function on its BIOS, for quicker screen transitions and to eliminate any residual tearing on crowded areas
  • Added CoolColors (the same palette I used on Gradius-2 smooth scroll) to improve the visuals on MSX2 or higher. These colors enhance the gradients and details of all MSX1 graphics.

As always, you can get it at this page.

Unfortunaly, no way to buy a digital version of this game. So it does not exist for me.

And one more announcement.

This patch implements the following bugfixes and enhancements to the game Mon Mon Monster by HOT-B:

  • Turbofixed the game
  • Faster screen-change routine
  • The game now passes the Acid2test. This also means that the FM soundtrack can now be heard on the MSX-Audio BIOS v1.3
  • New interrupt handler: quicker and more compliant
  • Enable the turbo on machines that have the CHGCPU routine on BIOS
  • The PSG can be redirected to the PSG emulator (requires MSX-Audio BIOS v1.3b, yet to be released). When this feature is enabled, the turbo will also be enabled automatically on Panasonic MSX2+ machines
  • Configuration keys that can be pressed on boot:
    • R = Enable the hidden F1 cheat to advance stages
    • 5 = Force 50Hz refresh rate, otherwise it will select 60Hz
    • P = Force PSG mode (don't detect MSX-Music or MSX-Audio)
    • O = Use PSG driver only (Allows PSG soundtrack on PSGemu)
    • M = Ignore internal MSX-Music
  • Added joyMega support:
    • START = pause
    • C button = throws rocks
  • Fixed a bug that caused writes to the OPLL to happen even when no MSX-Music was present
  • Fixed the "CONTENUE" typo of the game over screen

It can be downloaded at this page.

Guess what? Another announcement! Wink

This patch implement the following enhancements and fixes to the game Quarth, by Konami:

  • TurboFix: The game can now be run on turbo machines without any glitch
    • Fixed the splitscreen routine
    • Fixed the places where the CPU didn't wait for the blitter to finish
  • The turbo will be enabled via CHGCPU BIOS call on machines that support this
  • Correct handling of non-VDP interrupts, that are now passed along to the interrupt chain.
  • The game now passes the MSX Acid2Test: fixed routines on the Jukebox and battle-mode splitscreen
  • 50Hz video mode can be forced at boot by keeping the "5" key pressed.
  • The Button-2 of the joysticks can now be used to pause the game.
  • Partial Game Master 2 support. The ingame Game Master menu functions are glitchy, but the rest work fine.

It can be downloaded at this page.

There is a Steam version of Ghost called Mini Ghost.
...so you can own a digital version. While that one is not a true msx game, it does have a whole host of improvements.

Another announcement. While digging for the other releases, I bumped into this long forgotten project: Gradius-2 unfinished demo by FRS.

This is an unfinished demo I made back in 1992~1994. It was intended to show how this game could have looked if it had been released for the MSX2 instead of the MSX1. I rearranged myself all the art to the MSX2 using my Sharp Hotbit (upgraded to MSX2) and Graph Saurus 2.0, on a 14" CRT TV.

These are the images contained in the file:








And this is the video of the remade Metalion takeoff animation.
