Running the Rendition version

← About the game

The Rendition build of ICR2 is the best-looking version of the game — the one that originally required a Rendition Vérité 3D card. Today it runs on any modern PC through a Rendition wrapper. This guide follows the excellent tutorial by Golden Era Sim Racing.

This is a modern way to play — it wasn't available while the league was running in 2003–2007, when we launched the DOS game directly.

1. Download & install Rendition ICR2

Rendition requires a special version of Indycar Racing II. Download the ICR2REND package (basic game with Rendition updates) — or find and download the original Rendition version of the game elsewhere — and unzip the ICR2REND folder to a short path, e.g. C:\ICR2REND or C:\DOS\ICR2REND.

2. Get the Rendition wrapper

Two options:

Free wrapper — links are collected in this icr2.net forum thread.
Microsoft Store version — Rendition Wrapper (RLauncher), paid, with a convenient launcher app.

After installing, launch the app (e.g. RLauncher.exe on your Desktop).

3. Configure DOS settings

In RLauncher open the DOS Apps tab and click Select folder to install to.
Select the directory from step 1 (C:\ICR2REND etc.).
Click DosBox-Rendition Settings to open the DOSBox config. At minimum adjust the joystick section: under [joystick] set joysticktype=2axis if you have two controllers (wheel + pedals), or 4axis / 4axis_2 for a single controller. Consider removing the deadzone. DOSBox sees at most TWO controllers — HidHide can hide extra ones and JoyToKey can bind buttons on other devices.
At the bottom of the file, add under [autoexec] (adjust the mount path to where your ICR2REND folder lives — for C:\ICR2REND mount c:\, for C:\DOS\ICR2REND mount c:\DOS):

mount c c:\DOS
c:
cd ICR2REND
set SPEEDY3D=C:\ICR2REND
set SPEEDY3D_DMA=1
set SPEEDY3D_MEMSIZE=16
if exist INDYCAR.DMP del INDYCAR.DMP
INDYCAR > INDYCAR.DMP

Save and close the config file.

4. Configure Rendition settings

In RLauncher open Rendition Settings and set the options. Adjust Monitor Aspect Ratio to your screen (e.g. 21:9 for ultrawide), otherwise ICR2 will look squashed. Frame Generation and Vsync are optional. Click OK, then Launch on the DOS Apps tab. Enjoy!
