Demul 0.7a Arcade games
« on: July 10, 2015 - 01:27:58 »
Demul is the best emulator to play Dreamcast games. But you also can use it to emulating Arcade games (unMAMEd arcade games): Naomi, Naomi 2, Atomiswave, Hikaru, Gaelco and Cave. The emulation is very good.

Download the emulator (demul07a_230915) [You are not allowed to view links] Register or Login

Download roms and chds (you'll have two folders) (this forum don't have roms or chds)

Unrar the emulator. Run the emulator (demul.exe) as an administrator. Push OK and choose the following:
-VIDEO PLUGIN: GPUDX11NG
-SOUND PLUGIN: SPUDEMUL
-GD-ROM PLUGIN: GDRCHD
-CONTROLS PLUGIN: PADDEMUL
NETPLAY PLUGIN: NETDEMUL
ROMS AND BIOSES PATHS: Push ADD and choose roms folder. Again push ADD and choose chds folder
Push OK

Inside the emulator choose "Config" and "Controls", "Arcade Joy 1" and redefine the controls: only "Analog 1" for moviments. Push OK, OK and close the emulator.
Open file: "padDemul.ini". Go to [JAMMA0_0] section and copy all anolog numbers in digital controls. Close and save.

Run the emulator (demul.exe) as an administrator.

Inside the emulator choose "Config" and "Video":
RESOLUTION: our resolution
Select VSYNC
Select USE FULLSCREEN
APECT RATIO: 16:9 (or 4:3)
MAX LAYERS 64
Select N2 VERTEX CACHE if you have ATI/AMD GPU only
Deselect ENABLE TRANSLUCENT JOIN (TWEAKS section)
CV1K Blitter limit: it's for Cave shmups, less number makes bigger slowdowns in games
Push OK
Play a game. If there are slowdowns: modifies MAX LAYERS: 64 to 32

To leave Full screen while playing a game: ALT+ENTER

To exit while playing a game: ALT+F4

Sometimes when we play a game may have slowdowns at first

To choose another game language: inside the emulator, go to "CONFIG", "NAOMI BIOS", deselect "AUTO SELECT" and choose another BIOS (Naomi epr-21577g (USA))

Modify options game (difficult, lives,...): while playing push F4. F2 to move and F4 to select.


NOTE:
DX11NG is a new renderer plugin. The author says:
Quote
use "old" DX11 only if you need
- Gaelco emulation
- x2 x3 etc internal scaler
- shader filters
- Naomi rotated screen games
for other cases NG recommended, it is more optimised, more compatible, more bugfixed, etc

My recommendation: use GPUDX11NG except for GAELCO and vertical games

So, inside the emulator choose "Plugins and paths" and choose GPUDX11 (Video plugin). Push OK

Inside the emulator choose "Config" and "Video":

RESOLUTION: our resolution
Select VSYNC
Select USE FULLSCREEN
Select APECT RATIO: 16:9 (or 4:3)
INTERNAL RESOLUTION 2X
MAX LAYERS 32
SHADER EFFECTS: Select 1-PASS and 2-PASS and choose FXAA
HACKS: Deselect all
Push OK
Play a game (Inside the emulator choose FILE and one option). If there are slowdowns: select DISABLE TRANSLUCENT MODIFIER (HACKS section)
Play a game. If there are slowdowns: select DISABLE AUTO SORT (HACKS section)
Play a game. If there are slowdowns: deselect DISABLE TRANSLUCENT MODIFIER and DISABLE AUTO SORT and choose INTERNAL RESOLUTION 1X

Great stuff! I'm sure a lot of people would really love other configuration setups, I know some people take days/weeks getting their settings right in some GUIs!
Maybe some settings walkthroughs, and some archives of binaries and setups that are easy to run :)
Thanks for taking the time to write this, It'd come in useful for anyone who, like me, hasn't run dEmul, but only collects the ROMs! :)

If you have input lag, disable v-sync.
