(rsgdbfevx found fixes for several of these, but there’s still a lot of testing to do, and it wasn’t worth pushing back the Orbitus and airboard ditch fixes by potentially several months for the sake of this feature that most people probably don’t care about anyway!) A lot of these fixes that we had already prepared were shown in Simon’s stream on 19 September 2021, which also demonstrated the various problems with those fixes. Unfortunately tracking down every issue and fixing them without introducing more bugs proved to be infeasible in any reasonable amount of time, so the plan is to do a second patch down the line with the 100% thresholds fixed, if we can actually fix enough of them for it to matter. With this fix, these levels now function as intended for the first time since 1995.įinally, we wanted to fix one other issue in Jazz that has been present since its initial 1.0 release some levels are impossible to get 100% completion on. One wonders how these didn’t get used in the original release of 1.3! We were able to fix these levels, Turtemple 2 (LEVEL1.009) and Pezrock 2 (LEVEL1.015), by simply using the European 1.2 copies of these levels, which work just a treat in version 1.3. Two other airboard ditches actually functioned correctly in the European release of version 1.2, while the American release was just as broken as 1.3. With this fix, this level now functions as intended for the first time since 1994. I created a fix for this by simply giving the airboard ditch object in this level a small sprite that should be totally invisible to the player, as it will only display when Jazz is standing in front of it, and only for one frame, since after that Jazz picks it up like it’s an item, and drops his airboard. Many of these airboard ditches simply don’t work, such as the one in Medivo 1 (LEVEL0.002). That is, areas after you’ve picked up an airboard that should force you to drop them. This still left a few other problems namely, airboard ditches. With this fix, this level now functions as intended for the first time since at least 1995, although arguably this is the first time it’s ever worked as intended. This is easily the headline fix of this patch, and was the primary impetus behind us doing it. In the 1.2 update, this was broken because all the bounce floors in Orbitus were rendered non-functional in the European release of this version (often referred to as the “Good version”) a slightly janky fix was applied involving an invisible sprite called “quickfix” being added to the level, while the American release of 1.2 had no functional bounce floors at all! The more common version 1.3 remedied these problems (as well as a problem dating back to 1.0 that made it possible to fall through the bounce floors), but it also increased the vertical bounding box of the bounce floors so significantly that this one section was made nearly impossible. In earlier versions of the game, you could simply hold the right arrow and drift straight through this section trivially. Previous community fixes we’d seen had simply put up barriers to block the bounce ceiling that made the section near-impassable, but we chose to err on the side of recreating the experience of playing this level as it was in earlier, more functional versions (versions 1.0, 1.1, and the European release of 1.2 more on this later), so Simon moved a few of the bounce ceilings up slightly, and enlarged the opening you’re supposed to go through. Simon was the one to fix Orbitus 2 (aka LEVEL1.005). Subjective “improvements” may be the subject of a later J2O upload. ![]() We have avoided the temptation to try to “improve” the game (for instance, we didn’t open up the scrapped secret area in Sluggion 2) this is entirely a patch devoted to fixing issues in playing the game. ![]() The goal with this patch was to restore broken functionality, and fix other unintentional bugs. Our initial goal was to fix just a few core issues in the (then) final released version of Jazz Jackrabbit the infamous Orbitus 2 choke point, and the broken airboard ditches. The majority of the work on this patch was carried out by myself (Love & Thunder), with help by Simon (aka SimonNaar, Jazz speedrunner), some input from various users on the Jazz Discord (primarily rsgdbfevx), and some pointers from Violet CLM (Jazz 2+ developer, all-round awesome person), who is the reason this patch happened and got sent to GOG at all. This upload will remain useful for anyone who owns the game on CD, but if you own the game on GOG, it will not be necessary to download this. November 2021 edit: GOG has now published the update.
