A vehicle can have up to twice it's Body in armor (or three times Body rating for drones), up to a maximum of 20 for regular armor. This is right in the Armor mod entry, on page 133.

The Horizon-Doble Revolution has a Body of 6.

Sure thing, it is as follows:

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

- Optimized Cyberlimb options (Evo Kali, Louisville Slugger, etc) show "rating 4" in the selection window, but have no rating as they provide a static effect. It then displays as "rating 4" on the printout as well. These options have no rating, and there is no reason to have rating 4 on the printout as clutter either. If possible the rating selection, and the associated printout, should be removed for clarity.

- The Techonmancer Smartlink Complex Form is not being recognized as the "non gun half" of a Smartlink system. Using the cybereyes mod works, sunglasses work, contacts work, etc... but the Complex Form doesn't register as completing the system, resulting in the bonus dice not applying. For example, a Technomancer with the Pistols Skill, the Smartlink Complex Form, and an Ares Predator IV should get bonus dice but does not (but then does when he adds cybereyes or contacts etc).

- The "Armor", "Ranged Weapon", and "Melee Weapon" sections of the printout don't gray in the last cells in the lower right when displaying multi-line entries. Description of the issue is in the original post, I can also provide screen shots if desired.

- The Pistol Crossbow should be AP -, not AP -1

- Crossbow Ammo on the Light/Medium/Heavy Crossbows should be 4(m), not 1, per page 316 SR4. (This may apply to the pistol crossbow as well, but it is not explicitly stated as such one way or the other).

- There is no way to notate Cased ammo or Caseless Ammo. Perhaps adding a checkbox for Cased to the ammo entries would work, or having it ask which kind in a window similar to how it asks which category to use, or if neither of those works just adding more entries for caseless versions.

- Related, theres no way to specify Cased or Caseless Ammo Use for Firearms. Again, a checkbox would be great (and it could be locked on firearms which automatically require one type or the other).

- There is no Pistol Bolt (for the crossbow pistol) listed under ammo, only Regular Bolts. Its from Arsenal.

- The Injection Bolt should cost 30, not 50.

- The PJSS Rifle and Shotgun both only list SS as a firing type. However, they are SS/BF mechanically, the same as the Walther Palm Pistol. Why Catalyst chose to list them inconsistently in the books is beyond me, but I am confident it would be considered correct to adjust the PJSS entries to be SS/BF parallel to the Walther entry, as the rules are identical. If you opt not to, I understand, that is how they are presented in the books (certainly not the first inconsistency heh).

- Commlinks are stated to come with Earbuds on p327-328 SR4. However, there is no way to make an Earbuds accessory free when selecting one (thus allowing the commlink to have audio modifications etc). Perhaps a "free" checkbox should be added to the Earbuds to allow for this, or entries added to the Commlinks dropdown for "integral accessories" like "integral earbuds", "integral holoprojector", etc. There is a whole list of built-in features on those pages this could apply to, but Earbuds is by far the one which comes up most commonly. Note: I am referring to the character generation portion here, as there most certainly is a free button in career mode (but its hard to pay for the modifiers to something in creation mode when the base item is not yet there from career mode).

- Same issue with a Rating 1 Scan program. All wireless devices come with this for free by default, per p233 SR4 under Scan. It is useful to notate this one the character sheet so players are aware they can undertake actions which require it even if they miss the note on p233, and also so they don't forget to count it as a running program towards Response load. Again, a "free" checkbox, or "integral scan" listing in the programs would work. My favorite solution here is just a second Integral Scan program, stuck at rating 1 with Copy Protection and Registered, with a cost of 0... I am sure it is easier to add a single Gear listing than modify checkboxes in multiple places etc. Also, it would be easier to have one entry to add to anything wireless, than check to be sure no accidental free boxes were checked on other programs, at least in my opinion. Note: as above, referring to during creation.

- The Chemical Seal item has 10 uses, but displays as 1 item making it difficult to keep track of expenditures. I would suggest dividing the cost by 10, and adding the "Quantity" box (similar to something like ammo, or slap patches). Then, you can mark off uses as they are used, and let the "Qty" entry show the amount remaining, just like other things which are 'use and lose'.

Agents, IC, and autosofts may not be learned or used by technomancers.

Technomancers can not use autosoft, but character build allows them

Context: build 420, Windows 7 64 bit

After creating a brand new character with build 420, adding the technomancer quailty, and going to the compex forms and sprites page. It is possible to add autosoft complex forms to the build, although the rules do not allow that.

Actually that is not quite correct. As per Unwired p. 145 with the Biowire Echo they may emulate Skillsofts as complex forms like they had a skillwire cyberware. And as you could get echos at character creation using the Karma generation system, this option should remain in Chummer.

The Bows section in Weapons only lists bows up to Strength 8, when SR4A20 list them as having a maximum Strength of 12.

No solutions or suggestions on why I can't save to career mode, eh? *frown*

Skillsoft not equal autosoft
from RAW, autosoft never allowed, though as you say skillsoft is.

Actually the max of 8 is correct. If you look at the SR4A changes doc you'll see it referenced on the top right of page 4. You can find the document here: SR4A changes

Off hand I don't know where to find it on the Shadowrun site, I googled for it. But it is hosted on the real shadowrun website...

I checked my actual SR4A books (pdf and physical) and I know where you have the confusion. My physical book says 8, but the pdf says 12. I've heard that one of the original pdf's that was sent out had a few changes made to it before they even printed the first run of the actual book. For instance the Object Resistance Table has the same problem.

This prepares a vehicle to work in extreme environments, where unprepared vehicles will cease to function after a while or wouldn’t work at all (see Hazardous Environments, p. 163). The modification can be taken more often than once, each time for another environment (desert, polar, etc.). This adaptation is usually combined with an appropriate special armor modification (see p. 144). Note that adaptation for space or deep sea environments requires the life support modification (p. 138).

Yeah, this was a great source of confusion for a while. The printed SR4A book and the changes doc that's linked say they should be capped at STR 8. My pre-physical release copy of the book had them at max STR 12 as well. It appears though that they should be 8. If you want them to go up to 12, they can be easily added by creating a custom Weapons data file that just adds them in. (IMG:style_emoticons/default/smile.gif)

Just noticed a slight miscalculation when the response is calculated/reduced due to programs running:
Programs with the ergonomic option should not be calculated when counting the number of programs running (at least number of programs with ergonomic option equal to response)

Furthermore I think the number of programs allowed to run WITHOUT reducing the response should be equal to response, otherwise as it currently is, you cannot even run a single program on a response/system 1 device without reducing it to response 0 and therefore to a crawl according to fluff.

Street Cred is based on a chracter's total earned Karma (see Karma, p. 269), divided by 10 and rounded normally. A character who has earned 35 Karma in the course of a game will have a Street Cred of 4 (35 ÷ 10 = 3.5, rounded up to 4).
