History

GPDC started as a port of Genesis Plus by Charles Mac Donald. It's been in development since 2003 and a lot of progress has been made since then:

BlackAura rewrote the video renderer for the Dreamcast's PowerVR2. Stef D of wGens fame joined the project in 2004 to contribute fast and accurate CPU emulators: C68K & CZ80.

Now with Fox68K's new SH4 Z80 emulator FAZE, and FAME, a 68K emulator written in Dreamcast's SH4 assembly language, and BlackAura working on sound emulation, the project has reached its final stage. An official release is expected for the end of this year.


GPWT

Until then there's the preview version of GenesisPlusDC Warmtoe & BlackAura released in 07/2006.

It is called "GPWT" because it's been the first version to introduce a new GUI written by Warmtoe.

Button Layout

  • Mega Drive A-Button: (X)
  • Mega Drive B-Button: (A)
  • Mega Drive C-Button: (B)
  • Mega Drive X-Button: (L)
  • Mega Drive Y-Button: (Y)
  • Mega Drive Z-Button: (R)
  • Mega Drive Start-Button: (Start)


To exit a running game press (L) + (R) + (Start).


In the Menu

(Start) loads a game.

Pressing + holding (Up)/(Down) scrolls through your game list.

You can skip pages with (Left)/(Right) on the d-pad.

To disable/enable 6 button support, press (X).

To change the region settings, press (L).


CPU Settings

Some details about the different settings:

Pressing (B) at the menu changes the CPU emulator. You can select either

FAME - Fox68k's great SH4 M68K emulator for fastest emulation, or

C68K - Stef D's fast and accurate M68K emulator for better compatibility.


Video Settings

Press (A) to toggle the graphics renderer. You can select either

HW - Hardware renderer written by BlackAura, using the Dreamcast's PowerVR II DC, very fast but inaccurate in a few games, or

SW - Standard software renderer of GenesisPlusDC by Charles MacDonald, 100% accurate but much slower.


Recommend Settings

Recommend settings would be 'Render: HW' with 'CPU: FAME' - if this doesn't work for your game, try 'Render: HW' with 'CPU: C68K' (which is the default setting).


ROMS.TXT

Pretty straight from the readme:

In GPWT there is no directory browsing - just that fixed list of names for that fixed list of games.


You put your (zipped) ROMS in the directory:


\gpwt\data\ROMS


It also expects to find a file:


\gpwt\data\ROMS.txt


In ROMS.TXT you can put the names of your games in there plus the name you'd like to see displayed on screen:

SHINOBI.ZIP The Revenge of Shinobi

'SHINOBI.ZIP' (or 'shinobi.zip') would be your actual ROM, 'The Revenge of Shinobi' will be displayed on screen. Each file + name goes into a seperate line in ROMS.TXT.


Provlist by burnerO

An alternative would be Provlist by bO.

At first download this little tool set: http://www.dcevolution.net/dsdevelopment/large/CE/gpwt-tools.zip

Included are Provlist & Renamer which both are needed.

1. Copy your ROMs (*.zip) in /gpwt/data/ROMS/ and run Provlst.exe

2. Open ROMS.LST in Wordpad and replace ".SMC:" with ".ZIP " (space).

3. Save as 'ROMS.TXT' in /gpwt/data/

4. Right-click on your /gpwt/data/ROMS/ folder and start Renamer

5. Click on 'Edit' -> 'Multi-Change' and replace "%a.SMC" with "%a.ZIP"

6. Click on 'A->B' to apply the changes and then close Renamer

7. Burn the disc with BootDreams or SBInducer v4


Other Methods

Other methods to create a ROMS.TXT were discussed here.

How To Burn

A little tutorial:


Using Selfboot Inducer

  • Put this file into your C:/SBInducr/SBI/ folder.
  • Start C:/SBInducr/SBInducer.exe and check the SBI file showing up on the right window. Then select either "Single Menu" or "SBI2Boot" and click on 'Extract SBI'.
  • Using Windws Explorer you'll find some tools within the C:/SBInducr/Inducer/gpwt/tools/ directory. Extract "provlist_by_burnerO.zip" and copy "Provlst.exe" to C:/SBInducr/Inducer/gpwt/data/ROMS/
  • Copy your ROMs (*.zip) in C:/SBInducr/Inducer/gpwt/data/ROMS/ and run Provlst.exe
  • Open ROMS.LST in Wordpad and replace ".SMC:" with ".ZIP " (space).
  • Save as 'ROMS.TXT' in C:/SBInducr/Inducer/gpwt/data/.
  • Right-click on your C:/SBInducr/Inducer/gpwt/data/ROMS/ folder and start Renamer
  • Click on 'Edit' -> 'Multi-Change' and replace "%a.SMC" with "%a.ZIP"
  • Click on 'A->B' to apply the changes and then close Renamer
  • In Selfboot Inducer, click on the CDRecord button to burn the CD, or on the DiscJuggler button to create a .cdi that you can burn with BootDreams' CDI-burner or Alcohol120% in TAO mode.


Using BootDreams

Alternatively you could use BootDreams to burn the /Inducer/ folder:

  • Start BootDreams and point it to C:/SBInducr/Inducer/. It will then guide you to the process. I recommend the 'CDRecord' method.
