DogP released version 1.1 of his VB Sound Generator. It has a few minor changes in how values are processed, as well as a few other small changes. The source code is now also included.

Hey,

I decided to spend a little time this weekend putting together a VB sound generator, which attempts to be a cycle accurate VSU emulator. You give it an input file of register values and time delays, and it converts it to a wav file, and optionally outputs C code corresponding to the input sequence.

I've been wanting to do this for a long time... it just finally seemed like a good time to do it. There's a lot of reasons for it, the main one being that it's inconvenient to develop sounds by testing them on the VB to hear how they sound, and unfortunately Reality Boy isn't very accurate. I'm hoping in the long term that it may be possible to optimize this and roll it into RB, though that's not on my todo list yet.

What really started the project was wanting to know how the random noise generator worked (the manual specifies an LFSR, but it wasn't clear on what's actually output, and the tap locations, or notations, don't really make sense). The easiest and most for sure way for me to figure this out was to make a long recording and pull out the bit sequence. I did this by writing a MATLAB script to detect the first edge in the wav file, then sample 1/2 sample past that, and every sample beyond that. From that I got the LFSR bit sequences (which repeated as expected every time :-) ).

I'm guessing there will be bugs and inaccuracies (I haven't compared any of it with hardware yet, though it sounded good to my ear :-P).

I'm just posting the exe, example input file, and readme for now, though I'll post the source with the next version... so try it out and give me some feedback ;) . I'd also like a GUI for this... as much as I dislike Visual Basic, this actually seems like the perfect application for that... so we'll see. Of course if anyone else would like to do the GUI, that'd be great (but let me know so I don't start one ;-) ).

- Includes huge levels up to 29x32 blocks in Mini Mode
- Includes 9 languages: English, German, Spanish, Swedish, French, Italian, Slovenian, Finnish and Czech
- Save Battery support to save options, finished levels as well as an active game
- Full sound support with sound effects

Changed level 29. Should be done now. I've added a level select screen. Press select at the title screen to get to it, and left and right to choose a level and start to start.

level 8 has been fixed. It was impossible to beat.

I have to change some levels because of the sub's new size. I've done this up to level 9. I've added a level select screen. Press select at the title screen to get to it, and left and right to choose a level and start to start

There's a newer file where the collision detection works better.

In case you didn't know, I'm working on GoSub, this time for the Virtual Boy. I'm going to make it 2MB, hopefully room for 32 mazes. I don't know how to add sound, or flip the sprite so it's facing the right way, but here it is so far. 17 mazes. To get a level select screen, press SELECT at the title screen, or start at level 1 by pressing START. You can play this using the RealityBoy emulator, or use FlashBoy. If you decide to use FlashBoy, tell me how it runs on it.

I have release a demo version of my current Virtual Boy homebrew project BLOX 2, a Sokoban style puzzle game. Since changing to the latest gccVB version about 2 months ago, the game refused to run on hardware and I hadn't touched it since then. So I think it's a good idea to share the last build from before the change in form of a demo version. Features of the demo:

- 16 MBit ROM
- 3D Graphics
- Over 1500 Levels in 29 Level Sets by various homebrew level authors
- Undo Functionality
- Includes "Multiblox" levels (two players to solve a level, each controlled by a D-Pad)
- Includes huge levels up to 29x32 blocks in Mini Mode
- Includes 6 languages: English, German, Spanish, Swedish, French and Italian
- Save Battery support to save options, finished levels etc

Any feedback about the demo is appreciated and will help to release a polished final version.
