Story

Evil grows darkest in the shadow. This chapter comes to its evil conclusion with Heretic: Shadow of the Serpent Riders. In a twisted medieval dimension, undead creatures and bestial horrors have done the unthinkable - callously slaughtering your entire race.

But the nightmare has just begun. Wielding ungodly weapons such as the Firemace or Hellstaff and casting spells from the tomes of power, you must seek your vengeance...or die trying.

Changelog

2021/06/27

• Cleaned up the sound code. So far it seems to have resolved the odd sounds - screeches, crackling, etc.
• Made a change to clear the sound buffer and reset the sound timers during level changes. This should help with keeping the sound playback in sync with the mixer timer.
• Also merged the opl7 branch back into master - so master has the latest version.

2021/06/21

• Uploaded a new build to the opl7 branch. Adjusted the sprite scaling to reduce sprite texture loads. This has the benefit of fewer black lines at the expense of more aggressively scaled sprites, since sprites are almost always rendered in scaled down manner it is not super noticeable in most cases. The previous algorithm tried to avoid scaling down sprites when possible. The renderer supports dimensions of 8,32,64,128,256. The previous method would try to use first dimension that was greater than or equal to the actual sprite width/height. the new method scales down if it is halfway between two values. For instance widths between 64 and 96 will be scaled down to 64.

2021/06/20

• Upload a full rebuild new nds file. The last file may have been dldi patched for mpcf to work with desmume. Was having problem launching on a 3ds with the old build. There are no code changes, but it works now on 3ds.

2021/06/19

• Created a branch using different opl emulator code. The opl emulator code is from chocolate-doom which is in turn from dosbox.

2021/06/06

• Added a new version to git that should fix the e3m8 crash.

2021/05/29

• Added the automap to the bottom screen.

2021/05/28

• Disabled music.
• Added onscreen keyboard.
• Added R+L speed key.

2021/05/25

• Reverted texture loading code to use the previous method. Apparently the last commit was to add a new texture loading method - in an attempt to avoid black/white lines. This code has been reverted as it was intended for testing.
• Fixed sprite loading that caused an abort. This was caused by a cached object being evicted from the cache while it was still in use.
• Fixed music memory leak. mus files were never allowed to be dropped from the cache. This resulted in z_malloc failure errors.
• Reduced sfx from 16 to 8 in an attempt to reduce sound issues. Did not seem to make a difference.
• Added X+key combinations - you will need to delete heretic.cfg for this to take effect.

2021/05/21

• Updated the source so that it compiles and runs with the latest devkitARM and libnds.
• Also disabled god mode and adjusted the key bindings a little.
